Intel Arria 10 GX and GT Pin Connection Guidelines

Clock and PLL Pins

Note: Intel^® recommends that you create a Intel^® Quartus^® Prime design, enter your device I/O assignments, and compile the design. The Intel^® Quartus^® Prime software will check your pin connections according to I/O assignment and placement rules. The rules differ from one device to another based on device density, package, I/O assignments, voltage assignments, and other factors that are not fully described in this document or the device handbook.

Dedicated Configuration/JTAG Pins

Table 2. Dedicated Configuration/JTAG Pins
Pin Name	Pin Functions	Pin Description	Connection Guidelines
`nIO_PULLUP`	Input	Dedicated input pin that determines the internal pull-ups on user I/O pins and dual-purpose I/O pins (`DATA[0:31]`, `CLKUSR`, `INIT_DONE`, `DEV_OE`, and `DEV_CLRn`) are on or off before and during configuration. A logic high turns off the weak pull-up, while a logic low turns on the weak pull-up.	Tie the `nIO-PULLUP` pin directly to `VCC` using a 1 kΩ pull-up resistor, or directly to `GND`. This pin has an internal 25-kΩ pull-down. If you tie this pin to `VCC`, ensure all user I/O pins and dual-purpose I/O pins are at valid logic (0 or 1) after all the power supplies have reached full nominal voltage, before and during configuration.
`TEMPDIODEp`	Input	Pin used for temperature sensing diode (bias-high input) inside the FPGA.	If you do not use the temperature sensing diode with an external temperature sensing device, connect this pin to `GND`.
`TEMPDIODEn`	Input	Pin used for temperature sensing diode (bias-low input) inside the FPGA.	If you do not use the temperature sensing diode with an external temperature sensing device, connect this pin to `GND`.
`MSEL[0:2]`	Input	Configuration input pins that set the configuration scheme for the FPGA device.	These pins are internally connected through a 25-kΩ resistor to `GND`. Do not leave these pins floating. When these pins are unused, connect them to `GND`. Depending on the configuration scheme used, tie these pins to `VCCPGM` or `GND`. For more information about the configuration scheme options, refer to the Configuration, Design Security, and Remote System Upgrades for Intel^® Arria^® 10 Devices chapter. If you use JTAG configuration scheme, connect these pins to `GND`.
`nCE`	Input	Dedicated active-low chip enable pin. When the `nCE` pin is low, the device is enabled. When the `nCE` pin is high, the device is disabled.	In multi-device configuration, the `nCE` pin of the first device is tied low while its `nCEO` pin drives the `nCE` pin of the next device in the chain. In single-device configuration and JTAG programming, connect the `nCE` pin to `GND`.
`nCONFIG`	Input	Dedicated configuration control input pin. Pulling this pin low during user mode causes the FPGA to lose its configuration data, enter a reset state, and tri-state all I/O pins. Returning this pin to a logic high level initiates reconfiguration.	Connect the `nCONFIG` pin directly to the configuration controller when the FPGA uses a passive configuration scheme. Connect the `nCONFIG` pin through a 10-kΩ resistor tied to `VCCPGM` when the FPGA uses an active serial (AS) configuration scheme. If you do not use this pin, connect the pin directly or through a 10-kΩ resistor to `VCCPGM`.
`CONF_DONE`	Bidirectional (open-drain)	Dedicated configuration done pin. As a status output, the `CONF_DONE` pin drives low before and during configuration. After all configuration data is received without error and the initialization cycle starts, `CONF_DONE` is released. As a status input, the `CONF_DONE` pin goes high after all data is received. Then the device initializes and enters user mode. This pin is not available as a user I/O pin.	Connect an external 10-kΩ pull-up resistors to `VCCPGM`. `VCCPGM` must be high enough to meet the VIH specification of the I/O on the device and the external host. When you use passive configuration schemes, the configuration controller monitors this pin.
`nCEO`	I/O, Output (open-drain)	When device configuration is complete, the `nCEO` pin drives low. If you do not use this pin as a configuration pin, you can use this pin as a user I/O pin.	In multi-device configuration, the `nCEO` pin feeds the `nCE` pin of a subsequent FPGA. Connect this pin through an external 10-kΩ pull-up resistor to `VCCPGM`. In single-device configuration, you can leave this pin floating.
`nSTATUS`	Bidirectional (open-drain)	Dedicated configuration status pin. The FPGA drives the `nSTATUS` pin low immediately after power-up, and releases the pin after power-on reset (POR) time. As a status output, the `nSTATUS` pin is pulled low if an error occurs during configuration. As a status input, the device enters an error state when the `nSTATUS` pin is driven low by an external source during configuration or initialization. This pin is not available as a user I/O pin.	Connect an external 10-kΩ pull-up resistors to `VCCPGM`. `VCCPGM` must be high enough to meet the VIH specification of the I/O on the device and the external host. When you use passive configuration schemes, the configuration controller monitors this pin.
`TCK`	Input	Dedicated JTAG test clock input pin.	Connect this pin through a 1-kΩ pull-down resistor to `GND`. This pin has an internal 25-kΩ pull-down. Do not drive voltage higher than 1.8-, 1.5-, or 1.2-V `VCCPGM` supply for the `TCK` pin. The `TCK` input pin is powered by the `VCCPGM` supply.
`TMS`	Input	Dedicated JTAG test mode select input pin.	Connect this pin to a 1–10-kΩ pull-up resistor to `VCCPGM`. If the JTAG interface is not used, connect the `TMS` pin to `VCCPGM` using a 1-kΩ resistor. This pin has an internal 25-kΩ pull-up. Do not drive voltage higher than 1.8-, 1.5-, or 1.2-V `VCCPGM` supply for the `TMS` pin. The `TMS` input pin is powered by the `VCCPGM` supply.
`TDI`	Input	Dedicated JTAG test data input pin.	Connect this pin to a 1–10-kΩ pull-up resistor to `VCCPGM`. If the JTAG interface is not used, connect the `TDI` pin to `VCCPGM` using a 1-kΩ resistor. This pin has an internal 25-kΩ pull-up. Do not drive voltage higher than 1.8-, 1.5-, or 1.2-V `VCCPGM` supply for the `TDI` pin. The `TDI` input pin is powered by the `VCCPGM` supply.
`TDO`	Output	Dedicated JTAG test data output pin.	If the JTAG interface is not used, leave the `TDO` pin unconnected.
`TRST`	Input	Dedicated active low JTAG test reset input pin. The `TRST` pin is used to asynchronously reset the JTAG boundary-scan circuit.	Utilization of the `TRST` pin is optional. If you do not use this pin, tie this pin through a 1-kΩ pull-up resistor to `VCCPGM`. When you use this pin, ensure that the `TMS` pin is held high or the `TCK` pin is static when the `TRST` pin is changing from low to high. To disable the JTAG circuitry, tie this pin to `GND`. This pin has an internal 25-kΩ pull-up. Do not drive voltage higher than 1.8-, 1.5-, or 1.2-V `VCCPGM` supply for the `TRST` pin. The `TRST` input pin is powered by the `VCCPGM` supply.
`nCSO[0:2]`	Output	Dedicated output control signal from the FPGA to the EPCQ-L device in AS configuration scheme that enables the EPCQ-L device.	When you are not programming the FPGA in the AS configuration scheme, the `nCSO` pin is not used. When you do not use this pin as an output pin, leave this pin unconnected.

Optional/Dual-Purpose Configuration Pins

Table 3. Optional/Dual-Purpose Configuration Pins
Pin Name	Pin Functions	Pin Description	Connection Guidelines
`DCLK`	Input (PS, FPP); Output (AS)	Dedicated configuration clock pin. In passive serial (PS) and fast passive parallel (FPP) configuration schemes, `DCLK` is used to clock configuration data from an external source into the FPGA. In the AS configuration scheme, `DCLK` is an output from the FPGA that provides timing for the configuration interface.	Do not leave this pin floating. Drive this pin either high or low.
`CRC_ERROR`	I/O, Output (open-drain)	Active high signal indicates the error detection circuit has detected errors in the configuration RAM (CRAM) bits. Falling edge of this signal indicates the information about the error location and type are available in the error message register (EMR). This dual-purpose pin is only used when you enable error detection in user mode. This pin can be used as a user I/O pin.	When you use the open-drain output dedicated `CRC_ERROR` pin as an optional pin, connect this pin through an external 10-kΩ pull-up resistor to `VCCPGM`. When you do not use the open-drain output dual-purpose `CRC_ERROR` pin as an optional pin, and the `CRC_ERROR` pin is not used as an I/O pin, connect this pin as defined in the Intel^® Quartus^® Prime software.
`DEV_CLRn`	I/O, Input	Optional pin that allows you to override all clears on all device registers. When this pin is driven low, all registers are cleared. When this pin is driven high (`VCCPGM`), all registers behave as programmed.	When you do not use the dual-purpose `DEV_CLRn` pin and when this pin is not used as an I/O pin, tie this pin to `GND`.
`DEV_OE`	I/O, Input	Optional pin that allows you to override all tri-states on the device. When this pin is driven low, all I/O pins are tri-stated. When this pin is driven high (`VCCPGM`), all I/O pins behave as programmed.	When you do not use the dual-purpose `DEV_OE` pin and when this pin is not used as an I/O pin, tie this pin to `GND`.
`DATA0`	I/O, Input	Dual-purpose configuration data input pin. You can use the `DATA0` pin for PS or FPP configuration scheme, or as an I/O pin after configuration is complete.	When you do not use the dedicated input `DATA0` pin and when this pin is not used as an I/O pin, leave this pin unconnected.
`DATA[1:31]`	I/O, Input	Dual-purpose configuration data input pins. Use `DATA [1:7]` pins for FPP x8, `DATA [1:15]` pins for FPP x16, and `DATA [1:31]` pins for FPP x32 configuration or as regular I/O pins. These pins can also be used as user I/O pins after configuration.	When you do not use the dual-purpose `DATA[1:31]` pins and when these pins are not used as I/O pins, leave these pins unconnected.
`INIT_DONE`	I/O, Output (open-drain)	This is a dual-purpose pin and can be used as an I/O pin when not enabled as the `INIT_DONE` pin. When you enable this pin, a transition from low to high at the pin indicates the device has entered user mode. If the `INIT_DONE` output is enabled, the `INIT_DONE` pin cannot be used as a user I/O pin after configuration.	When you use the optionally open-drain output dedicated `INIT_DONE` pin, connect this pin to an external 10-kΩ pull-up resistor to `VCCPGM`. When you use this pin in an AS or PS multi-device configuration mode, ensure you enable the `INIT_DONE` pin in the Intel^® Quartus^® Prime designs. When you do not use the dedicated `INIT_DONE` optionally open-drain output, and when this pin is not used as an I/O pin, connect this pin as defined in the Intel^® Quartus^® Prime software.
`nPERST[L,R][0:1]`	I/O, Input	Dual-purpose fundamental reset pin that is only available when you use together with PCI Express* (PCIe*) hard IP (HIP). When the pin is low, the transceivers are in reset. When the pin is high, the transceivers are out of reset. When you do not use this pin as the fundamental reset, you can use this pin as a user I/O pin.	Connect this pin as defined in the Intel^® Quartus^® Prime software. This pin is powered by 1.8V VCCIO supply and must be driven by 1.8V compatible I/O standards. Connect the PCIe `nPERST` pin to a level translator to shift down the voltage from 3.3V LVTTL to 1.8V to interface with this pin. When this pin is not used for configuration purpose, you have the option to select 1.2V, 1.5V, or 1.8V compatible I/O standard. However, you must shift down the 3.3V LVTTL voltage from the PCIe `nPERST` pin to the selected Intel^® Arria^® 10 `nPERST` I/O standard voltage level. Only one `nPERST` pin is used per PCIe HIP. The Intel^® Arria^® 10 components always have all four pins listed even when the specific component might only have 1 or 2 PCIe HIPs. `nPERSTL0` = Bottom Left PCIe HIP & CvP `nPERSTL1` = Top Left PCIe HIP (When available) `nPERSTR0` = Bottom Right PCIe HIP (When available) `nPERSTR1` = Top Right PCIe HIP (When available) For maximum compatibility, always use the bottom left PCIe HIP first, as this is the only location that supports Configuration via Protocol (CvP) using the PCIe link.
`AS_DATA0/ASDO`	Bidirectional	Dedicated AS configuration pin. When using an EPCQ-L device (x1 mode), this is the `ASDO` pin and is used to send address and control signals between the FPGA device and the EPCQ-L device.	When you do not program the device in the AS configuration mode, the `ASDO` pin is not used. When you do not use this pin, leave the pin unconnected.
`AS_DATA[1:3]`	Bidirectional	Dedicated AS configuration data pins. Configuration data is transported on these pins when connected to the EPCQ-L devices.	When you do not use this pin, leave the pin unconnected.

`PR_REQUEST`	I/O, Input	Partial reconfiguration request pin. Drive this pin high to start partial reconfiguration. Drive this pin low to end reconfiguration. You can only use this pin in partial reconfiguration using an external host mode in FPP x16 configuration scheme.	Leaving the `PR_REQUEST` pin floating may cause configuration error. Drive this pin low during configuration whether you use this pin as a partial reconfiguration pin. This pin is reserved as an input with a weak pull-up during configuration. When you do not use this pin as the dedicated input `PR_REQUEST` pin, and when this pin is not used as an I/O pin, tie this pin to `GND`. You can use the `PR_REQUEST` pin as an I/O pin. If this pin is used as input pin, the host or external component connected to this pin must drive this pin low during device configuration.
`PR_READY`	I/O, Output or Output (open-drain)	The partial reconfiguration ready pin is driven low until the device is ready to begin partial reconfiguration. When the device is ready to start reconfiguration, this signal is released and pulled high by an external pull-up resistor.	When you use as optionally open-drain output dedicated `PR_READY` pin, connect this pin to an external 10-kΩ pull-up resistor to `VCCPGM`. When you do not use as the dedicated `PR_READY` optionally open-drain output, and when this pin is not used as an I/O pin, connect this pin as defined in the Intel^® Quartus^® Prime software.
`PR_ERROR`	I/O, Output or Output (open-drain)	The partial reconfiguration error pin is driven low during partial reconfiguration unless the device detects an error. If an error is detected, this signal is released and pulled high by an external pull-up resistor.	When you use as optionally open-drain output dedicated `PR_ERROR` pin, connect this pin to an external 10-kΩ pull-up resistor to `VCCPGM`. When you do not use as the dedicated `PR_ERROR` optionally open-drain output, and when this pin is not used as an I/O pin, connect this pin as defined in the Intel^® Quartus^® Prime software.
`PR_DONE`	I/O, Output or Output (open-drain)	The partial reconfiguration done pin is driven low until the partial reconfiguration is complete. When the reconfiguration is complete, this signal is released and pulled high by an external pull-up resistor.	When you use as optionally open-drain output dedicated `PR_DONE` pin, connect this pin to an external 10-kΩ pull-up resistor to `VCCPGM`. When you do not use as the dedicated `PR_DONE` optionally open-drain output, and when this pin is not used as an I/O pin, connect this pin as defined in the Intel^® Quartus^® Prime software.
`CvP_CONFDONE`	I/O, Output (open-drain)	CvP done pin is driven low during configuration. When the CvP configuration is complete, this signal is released and pulled high by an external pull-up resistor. Status of this pin is only valid if the `CONF_DONE` pin is high.	When you use as optionally open-drain output dedicated `CvP_CONFDONE` pin, connect this pin to an external 10-kΩ pull-up resistor to `VCCPGM`. When you do not use as the dedicated `CvP_CONFDONE` optionally open-drain output, and when this pin is not used as an I/O pin, connect this pin as defined in the Intel^® Quartus^® Prime software.

`RZQ_[#]` , `VID_EN`	I/O	Reference pins for I/O banks. The RZQ pins share the same `VCCIO` with the I/O bank where they are located. Connect the external precision resistor to the designated pin within the bank. If not required, this pin is a regular I/O pin.	When using OCT tie these pins to `GND` through either a 240-Ω or 100-Ω resistor, depending on the desired OCT impedence. Refer to the Intel^® Arria^® 10 Device Handbook for the OCT impedence options for the desired OCT scheme. If you are using the Early I/O Release feature in the Intel^® Arria^® 10 SX devices, ensure that this pin is located within the active HPS I/O banks. For more information, refer to the HPS EMIF Design Consideration chapter of the Intel^® Arria^® 10 SoC Design Guidelines.
`RZQ_[#]` , `VID_EN`	I/O	The `VID_EN` pin is not a physical pin. The `VID_EN` pin is a multi-function shared pin with the `RZQ_2A` pin.	If you are using the SmartVID feature, you have the option to enable the `VID_EN` function using the `RZQ_2A` pin. If you use the `RZQ_2A` pin as the `VID_EN` pin, you cannot use the `RZQ_2A` pin for OCT calibration. If you are using the `RZQ_2A` pin for OCT calibration, you have the option to use other available general-purpose I/O pins for the `VID_EN` function.
`DNU`	Do Not Use	Do Not Use (`DNU`).	Do not connect to power, `GND`, or any other signal. These pins must be left floating.
`NC`	No Connect	Do not drive signals into these pins.	When designing for device migration, you have the option to connect these pins to either power, `GND`, or a signal trace depending on the pin assignment of the devices selected for migration. However, if device migration is not a concern, leave these pins floating.

Supply Pins

Table 9. Supply Pins
Pin Name	Pin Functions	Pin Description	Connection Guidelines
`VCCP`	Power	`VCCP` supplies power to the periphery.	`VCC`, `VCCP`, and `VCCERAM` must operate at the same voltage level, should share the same power plane on the board, and be sourced from the same regulator unless the SmartVID feature is used, as described below. You can operate -1 and -2 speed grade devices at 0.9V or 0.95V typical value. You can operate -3 speed grade device only at 0.9V typical value.

For more information about the performance and power consumption, refer to the Intel^® Quartus^® Prime software timing reports and Intel^® Arria^® 10 Early Power Estimator (EPE). For details about the recommended operating conditions, refer to the Electrical Characteristics in the device datasheet. Use the Intel^® Arria^® 10 Early Power Estimator (EPE) to determine the current requirements for `VCCP` and other power supplies. Decoupling for these pins depends on the decoupling requirements of the specific board. See Notes 2, 3, 4, 5, 6, and 10.
`VCC`	Power	`VCC` supplies power to the core. `VCC` also supplies power to the Hard IP for PCI Express cores.	`VCC`, `VCCP`, and `VCCERAM` must operate at the same voltage level, should share the same power plane on the board, and be sourced from the same regulator unless the SmartVID feature is used, as described below. You can operate -1 and -2 speed grade devices at 0.9V or 0.95V typical value. You can operate -3 speed grade device only at 0.9V typical value. Operating at 0.95V results in higher core performance and higher power consumption. For more information about the performance and power consumption, refer to the Intel^® Quartus^® Prime software timing reports and Intel^® Arria^® 10 Early Power Estimator (EPE).

`VCCPT`	Power	Power supply for the programmable power technology and I/O pre-drivers.	Connect `VCCPT` to a 1.8V low noise switching regulator. You have the option to source the following from the same regulator as `VCCPT`: `VCCH_GXB`, `VCCA_PLL`, `VCCPLL_HPS` with proper isolation filtering `VCCIOREF_HPS` `VCCBAT` if it is using the same voltage level and the design security key feature is not required If you are not using HPS, do not share `VCCPLL_HPS` and `VCCIOREF_HPS` with `VCCPT`. Provide a minimum decoupling of 1uF for the `VCCPT` power rail near the `VCCPT` pin. For the power rail sharing, refer to the Power Supply Sharing Guidelines for Intel^® Arria^® 10 Devices. See Notes 2, 3, 4, 7, and 10.
`VCCA_PLL`	Power	PLL analog power.	Connect `VCCA_PLL` to a 1.8V low noise switching regulator. With proper isolation filtering, you have the option to source `VCCA_PLL` from the same regulator as `VCCPT`. See Notes 2, 3, 4, 7, and 10.
`VCCIO([2][A, F,G,H,I,J,K, L, AF, KL], [3][A, B,C,D,E,F,G, H, AB, GH])`	Power	These are I/O supply voltage pins for banks 1 through 12. Each bank can support a different voltage level. Supports VCCIO standards that include Diff HSTL/HSTL(12, 15, 18), Diff SSTL/SSTL(12, 125, 135, 15, 18), Diff HSUL/HSUL(12), Diff POD 12, LVDS/Mini_LVDS/RSDS, 1.2V, 1.5V, 1.8V, 2.5V, 3.0V I/O standards.	Connect these pins to 1.2V, 1.25V, 1.35V, 1.5V, 1.8V, 2.5V, or 3.0V supplies, depending on the I/O standard required by the specified bank. When these pins require the same voltage level as `VCCPGM`, you have the option to tie them to the same regulator as `VCCPGM`. Not all I/O banks support 2.5V or 3.0V supplies. Not all devices support 3.0V I/O standard. For more details, refer to the I/O and High Speed I/O in Intel^® Arria^® 10 Devices. For the power rail sharing, refer to the Power Supply Sharing Guidelines for Intel^® Arria^® 10 Devices. See Notes 2, 3, 4, 8, and 10.
`VCCPGM`	Power	Configuration pins power supply.	Connect these pins to a 1.2V, 1.5V, or 1.8V power supply. When dual-purpose configuration pins are used for configuration, tie `VCCIO` of the bank to the same regulator as `VCCPGM`, ranging from 1.2V, 1.5V, or 1.8V. When you do not use dual-purpose configuration pins for configuration, connect `VCCIO` to 1.2V, 1.25V, 1.35V, 1.5V, or 1.8V. When these pins require the same voltage level as `VCCIO`, you have the option to tie them to the same regulator as `VCCIO`. Provide a minimum decoupling of 47nF for the `VCCPGM` power rail near the `VCCPGM` pin. For the power rail sharing, refer to the Power Supply Sharing Guidelines for Intel^® Arria^® 10 Devices. See Notes 2, 3, 4, and 10.
`VCCERAM`	Power	Memory power pins.	Connect all `VCCERAM` pins to a 0.9V or 0.95V linear or low noise switching power supply. You have the option to share `VCCL_HPS` with `VCCERAM` plane if the `VCCL_HPS` voltage is at the same level for Intel^® Arria^® 10 SX devices. `VCC`, `VCCP`, and `VCCERAM` must operate at the same voltage level, should share the same power plane on the board, and be sourced from the same regulator. When sharing the same regulator for `VCCERAM`, `VCC`, and `VCCP`, the SmartVID feature is not available. If you use the SmartVID feature, then `VCC` and `VCCP` need to be sourced by a dedicated regulator that is separate from the `VCCERAM` regulator. When you use the SmartVID feature, `VCCERAM` must be equal to 0.9V. See Notes 2, 3, 7, and 10.
`VCCBAT`	Power	Battery back-up power supply for design security volatile key register.	When using the design security volatile key, connect this pin to a non-volatile battery power source in the range of 1.2V - 1.8V. When not using the volatile key, tie this pin to a supply ranging from more than 1.5V to 1.8V. If 1.8V is selected when the design security key is unused, you have the option to source this pin from the same regulator as `VCCPT`. This pin must be properly powered as per the recommended voltage range as the POR circuitry of the Intel^® Arria^® 10 devices monitoring `VCCBAT`. Provide a minimum decoupling of 47nF for the `VCCBAT` power rail near the `VCCBAT` pin. For the power rail sharing, refer to the Power Supply Sharing Guidelines for Intel^® Arria^® 10 Devices.
`GND`	Ground	Device ground pins.	All `GND` pins should be connected to the board ground plane.
`VREFB[[2][A, F,G,H,I,J,K, L], [3][A, B,C,D,E,F,G, H]]N0`	Power	Input reference voltage for each I/O bank. If a bank uses a voltage-referenced I/O standard, then use these pins as voltage-reference pins for the bank.	If `VREF` pins are not used, connect them to either the `VCCIO` in the bank in which the pin resides or `GND`. See Notes 2, 8, 10, and 11. The following lists the four pairs of `VREF` pins in the RF40 package of the Intel^® Arria^® 10 GX devices that must be connected to the same voltage source on the board: `VREFB2AN0` and `VREFB2FN0` `VREFB2KN0` and `VREFB2LN0` `VREFB3AN0` and `VREFB3BN0` `VREFB3GN0` and `VREFB3HN0`
`VCCLSENSE`	Power	Differential sense line to external regulator.	`VCCLSENSE` and `GNDSENSE` are differential remote sense pins for the `VCC` power. Connect your regulators’ differential remote sense lines to the respective `VCCLSENSE` and `GNDSENSE` pins. This compensates for the DC IR drop associated with the PCB and device package from the `VCC` power. Route these connections as differential pair traces and keep them isolated from any other noise source. Connect `VCCLSENSE` and `GNDSENSE` lines to the regulator’s remote sense inputs when I_CC current >30A or when the SmartVID feature is used. `VCCLSENSE` and `GNDSENSE` line connections are optional if I_CC current <=30A and the SmartVID feature is not used. However, Intel^® recommends connecting the `VCCLSENSE` and `GNDSENSE` for regulators that support remote sense line feature. If you do not use the `VCCLSENSE` and `GNDSENSE` pins, leave the `VCCLSENSE` and `GNDSENSE` pins unconnected.
`GNDSENSE`	Ground	Differential sense line to external regulator.
`ADCGND`	Ground	Dedicated quiet ground.	If you are using voltage sensor, you must connect `ADCGND` plane to board `GND` through a proper isolation filter with ferrite bead. Select the ferrite bead according to the frequency of the noise profile when it shows the maximum noise level. Alternatively, you can choose the ferrite bead based on the `ADCGND` maximum current value as well, which is 10 mA. If you are not using voltage sensor, isolation filter with ferrite bead to board `GND` is optional.

Transceiver Pins

Pin Name	Pin Functions	Pin Description	Connection Guidelines
`VCCR_GXB[L1,R4] [C,D,E,F,G,H,I,J]`	Power	Analog power, receiver, specific to each transceiver bank of the left (L) side or right (R) side of the device.	Connect `VCCR_GXB` pins to a 0.95V, 1.03V, or 1.12V low noise switching regulator. 1.12V is applicable only for Intel^® Arria^® 10 GT devices. For transceivers data rates in respect to each voltage level, refer to the Notes to Power Supply Sharing Guidelines. If all of the transceivers, fPLLs, and IOPLLs on a side are not used, then the `VCCR_GXB` power rails of those inner banks on that side can be tied to `GND` to save power. The two outer banks on either the left or right side must always be powered on for proper operation of the device. The outer banks are always the first bank (lowest alphabetical letter) and last bank (highest alphabetical letter) on a side. Example 1—Device with 8 transceiver banks on a side. `VCCR_GXB1J`—left side top outer bank. Do not power down. `VCCR_GXB1I` `VCCR_GXB1H` `VCCR_GXB1G` `VCCR_GXB1F` `VCCR_GXB1E` `VCCR_GXB1D` `VCCR_GXB1C`—left side bottom outer bank. Do not power down. `VCCR_GXB4J`—right side top outer bank. Do not power down. `VCCR_GXB4I` `VCCR_GXB4H` `VCCR_GXB4G` `VCCR_GXB4F` `VCCR_GXB4E` `VCCR_GXB4D` `VCCR_GXB4C`—right side bottom outer bank. Do not power down. Example 2—Device with 4 transceiver banks on a side. `VCCR_GXB1F`—left side top outer bank. Do not power down. `VCCR_GXB1E` `VCCR_GXB1D` `VCCR_GXB1C`—left side bottom outer bank. Do not power down. `VCCR_GXB4F`—right side top outer bank. Do not power down. `VCCR_GXB4E` `VCCR_GXB4D` `VCCR_GXB4C`—right side bottom outer bank. Do not power down. `VCCR_GXB` pins on the same side of the device must have the same voltage. The `VCCT_GXB` and `VCCR_GXB` power supplies voltage level must be equivalent if both power supplies are powered on. See Notes 2, 3, 4, 7, and 10.
`VCCT_GXB[L1,R4] [C,D,E,F,G,H,I,J]`	Power	Analog power, transmitter, specific to each transceiver bank of the left (L) side or right (R) side of the device.	Connect `VCCT_GXB` pins to a 0.95V, 1.03V, or 1.12V low noise switching regulator. 1.12V is applicable only for Intel^® Arria^® 10 GT devices. For transceivers data rates in respect to each voltage level, refer to the Notes to Power Supply Sharing Guidelines. If all of the transceivers, fPLLs, and IOPLLs on a side are not used, then the `VCCT_GXB` power rails on that side can be tied to `GND` to save power regardless of whether they are an inner or outer bank. `VCCT_GXB` pins on the same side of the device must have the same voltage. The `VCCT_GXB` and `VCCR_GXB` power supplies voltage level must be equivalent if both power supplies are powered on. See Notes 2, 3, 4, 7, and 10.
`VCCH_GXB[L,R]`	Power	Analog power, block level transmitter buffers, specific to the left (L) side or right (R) side of the device.	Connect `VCCH_GXB` to 1.8V low noise switching regulator. With a proper isolation filtering, you have the option to source `VCCH_GXB` from the same regulator as `VCCPT`. All `VCCH_GXB` of all transceiver banks must be powered on for proper device operation except for the HF34 and NF40 packages of the Intel^® Arria^® 10 GX and GT devices. For the HF34 and NF40 packages of the Intel^® Arria^® 10 GX and GT devices, the `VCCH_GXBR` power rails can be tied to GND to save power if all of the transceivers, fPLLs, and IOPLLs on that side are not used. `VCCH_GXB` pins on the same side of the device must have the same voltage. Provide a minimum decoupling of 2.2nF for the `VCCH_GXB` power rail near the `VCCH_GXB` pin. To reduce voltage regulator module (VRM) switching noise impact on channel jitter performance, the VRM switching frequency for the `VCCH_GXB` rail should be below 2 MHz. For OTN application, the VRM switching frequency for the `VCCH_GXB` rail should be below 500 KHz. See Notes 2, 3, 4, 7, and 10.
`GXB[L1,R4][C,D,E,F,G,H,I,J]_RX_[0:5]p` , `GXB[L,R][1][C,D,E,F,G,H,I,J]_REFCLK_CH[0:5]p`	Input	High speed positive differential receiver channels. Specific to each transceiver bank of the left (L) side or right (R) side of the device.	These pins can be AC-coupled or DC-coupled when used. Connect all unused `GXB_RXp` pins directly to `GND`, `VCCR_GXB`, or `VCCT_GXB` pins.
`GXB[L1,R4][C,D,E,F,G,H,I,J]_RX_[0:5]n` , `GXB[L,R][1][C,D,E,F,G,H,I,J]_REFCLK_CH[0:5]n`	Input	High speed negative differential receiver channels. Specific to each transceiver bank of the left (L) side or right (R) side of the device.	These pins can be AC-coupled or DC-coupled when used. Connect all unused `GXB_RXn` pins directly to `GND`.
`GXB[L1,R4][C,D,E,F,G,H,I,J]_TX_CH[0:5]p`	Output	High speed positive differential transmitter channels. Specific to each transceiver bank of the left (L) side or right (R) side of the device.	Leave all unused `GXB_TXp` pins floating.
`GXB[L1,R4][C,D,E,F,G,H,I,J]_TX_CH[0:5]n`	Output	High speed negative differential transmitter channels. Specific to each transceiver bank of the left (L) side or right (R) side of the device.	Leave all unused `GXB_TXn` pins floating.

These pins must be AC-coupled if the selected REFCLK I/O standard is not HCSL. In the PCI Express configuration, DC-coupling is allowed on the `REFCLK` if the selected REFCLK I/O standard is HCSL. Connect all unused pins either individually to `GND` or tie all unused pins together through a single 10-kΩ resistor to `GND`. Ensure that the trace from the pins to the resistor(s) are as short as possible. See Note 9.
`REFCLK_GXB[L1,R4][C,D,E,F,G,H,I,J]_CH[B,T]n`	Input	High speed differential reference clock complement, complementary receiver channel, specific to each transceiver bank of the left (L) side or right (R) side of the device. `REFCLK_GXB` can be used as dedicated clock input pins with fPLL for core clock generation even when the transceiver channel is not available.	These pins must be AC-coupled if the selected REFCLK I/O standard is not HCSL. In the PCI Express configuration, DC-coupling is allowed on the `REFCLK` if the selected REFCLK I/O standard is HCSL. Connect all unused pins either individually to `GND` or tie all unused pins together through a single 10-kΩ resistor to `GND`. Ensure that the trace from the pins to the resistor(s) are as short as possible. See Note 9.
`CLKUSR`	I/O	This pin is used as the clock for transceiver calibration, and is a mandatory requirement when using transceivers. This pin is optionally used for Hybrid Memory Cube (HMC) calibration, as well as a configuration clock input for synchronizing the initialization of more than one device. This is a user-supplied clock and the input frequency range must be in the range from 100 MHz to 125 MHz. This pin can be used as a GPIO pin only if you are not using transceivers, not using HMC, and not using this pin as a user-supplied configuration clock.	If you are using the `CLKUSR` pin for configuration and transceiver calibration, you must supply an external free running and stable clock to the `CLKUSR` pin at start of device configuration and also when the device entered user mode. If the clock is not present at device power-up, transceiver calibration will be delayed until the clock is available. This may impact protocol compliance. You need to ensure supplying the `CLKUSR` pin with a common clock frequency that is applicable for both the configuration mode and transceiver calibration.
			If you are not using the `CLKUSR` pin for configuration but using the `CLKUSR` pin for transceiver calibration, you must supply an external free running and stable clock to the `CLKUSR` pin at start of device configuration and also when the device entered user mode. If the clock is not present at device power-up, transceiver calibration will be delayed until the clock is available. This may impact protocol compliance.
			If you are using the `CLKUSR` pin for configuration but not using the `CLKUSR` pin for transceiver calibration, you must use a user-supplied clock input. For more information, refer to the Configuration, Design Security, and Remote System Upgrades for Intel^® Arria^® 10 Devices chapter.
			Connect the `CLKUSR` pin to `GND` if you are not using the `CLKUSR` pin for any of the following: Configuration clock input Transceiver calibration clock An I/O pin
`RREF_[T,B][L,R]`	Input	Reference resistor for fPLL, IOPLL, and transceiver, specific to the top (T) side or bottom (B) side and left (L) side or right (R) side of the device.	If any `REFCLK` pin or transceiver channel on one side (left or right) of the device or IOPLL is used, you must connect each `RREF` pin on that side of the device to its own individual 2kΩ resistor to `GND`. Otherwise, you can connect each `RREF` pin on that side of the device directly to `GND`. In the PCB layout, the trace from this pin to the resistor needs to be routed so that it avoids any aggressor signals.

Notes to Intel Arria 10 GX and GT Pin Connection Guidelines

Intel^® provides these guidelines only as recommendations. It is the responsibility of the designer to apply simulation results to the design to verify proper device functionality.

These pin connection guidelines are created based on the Intel^® Arria^® 10 GX and GT device variants.
Select the capacitance values for the power supply after you consider the amount of power they need to supply over the frequency of operation of the particular circuit being decoupled. Calculate the target impedance for the power plane based on current draw and voltage drop requirements of the device/supply. Then, decouple the power plane using the appropriate number of capacitors. On-board capacitors do not decouple higher than 100 MHz due to “Equivalent Series Inductance” of the mounting of the packages. Consider proper board design techniques such as interplane capacitance with low inductance for higher frequency decoupling. Refer to the PDN tool.
Use the Intel^® Arria^® 10 Early Power Estimator (EPE) to determine the current requirements for VCC and other power supplies. Use the Intel^® Quartus^® Prime Power Analyzer for the most accurate current requirements for this and other power supplies.
These supplies may share power planes across multiple Intel^® Arria^® 10 devices.
Power pins should not share breakout vias from the BGA. Each ball on the BGA needs to have its own dedicated breakout via. VCC must not share breakout vias.
Example 1 through Example 7 and Figure 1 through Figure 7 illustrate the power supply sharing guidelines for the Intel^® Arria^® 10 GX and Intel^® Arria^® 10 GT devices. Example 11 illustrates the power supply sharing guidelines for Intel^® Arria^® 10 GX device using the SmartVID feature.
Low Noise Switching Regulator—defined as a switching regulator circuit encapsulated in a thin surface mount package containing the switch controller, power FETs, inductor, and other support components. The switching frequency is usually between 800kHz and 1MHz and has fast transient response. The switching frequency range is not an Intel^® requirement. However, Intel^® does require the Line Regulation and Load Regulation meet the following specifications:
- Line Regulation < 0.4%
- Load Regulation < 1.2%
The number of modular I/O banks on Intel^® Arria^® 10 devices depends on the device density. For the indexes available for a specific device, please refer to the I/O Bank section in the Intel^® Arria^® 10 Device Handbook.
For AC-coupled links, the AC-coupling capacitor can be placed anywhere along the channel. PCI Express protocol requires the AC-coupling capacitor to be placed on the transmitter side of the interface that permits adapters to be plugged and unplugged.
Decoupling for these pins depends on the design decoupling requirements of the specific board.
Do not connect voltage above 1.8V to the VREFB[[2][A, F,G,H,I,J,K, L], [3] [A, B,C,D,E,F,G, H]]N0 pins. For 3V I/O banks, tie unused VREF pins to GND.
Do not drive the I/O pins externally during the power-up and power-down time to avoid excess current on the I/O pins:
- Excess I/O pin current affects the device's lifetime and reliability.
- Excess current on the 3V I/O pins can damage the Intel^® Arria^® 10 device.
For the acceptable limits on the input current, refer to the Absolute Maximum Ratings section in the Intel^® Arria^® 10 Device Datasheet.

HPS Supply Pins

Table 11. HPS Supply Pins
HPS Pin Name	Pin Functions	Pin Description	Connection Guidelines
`VCCL_HPS`	Power	`VCCL_HPS` supplies power to the HPS core.	Connect all `VCCL_HPS` pins to a 0.9V or 0.95V low noise switching regulator. For more information about the voltage requirements for various operating temperatures and speed grades, refer to the Maximum HPS Clock Frequencies Across Device Speed Grade for Intel^® Arria^® 10 Devices table in the Intel^® Arria^® 10 Device Datasheet. Use the Intel^® Arria^® 10 Early Power Estimator (EPE) to determine the current requirements for `VCCL_HPS` and other power supplies. Decoupling for these pins depends on the design decoupling requirements of the specific board. See Notes 2, 3, 4, and 6.
`VCCIO_HPS`	Power	HPS dedicated I/Os can support a different voltage level from 1.8V to 3.0V. The supported I/O standard is LVTTL/ LVCMOS (3.0, 2.5, 1.8).	Connect these pins to a 1.8V, 2.5V, or 3.0V power supply, depending on the I/O standard required by the specified bank. If these pins have the same voltage requirement as `VCCIO` and `VCCPGM`, you have the option to source `VCCIO_HPS` pins from the same regulator as `VCCIO` and `VCCPGM`. Decoupling for these pins depends on the design decoupling requirements of the specific board. See Notes 2, 3, 4, and 8.
`VCCPLL_HPS`	Power	`VCCPLL_HPS` supplies analog power to the HPS core PLLs.	Connect these pins to a 1.8V low noise switching power supply through a proper isolation filter. Share `VCCPLL_HPS` with the same regulator as `VCCPT` when all power rails require 1.8V but only with a proper isolation filter. Decoupling for these pins depends on the design decoupling requirements of the specific board. See Notes 2, 3, 4, and 7.
`VCCIOREF_HPS`	Power	HPS power supply for I/O pre-drivers.	The `VCCIOREF_HPS` pins require 1.8V. When these pins have the same voltage requirements as `VCCIO_HPS`, you have the option to tie them to the same regulator. If these pins have the same voltage requirement as `VCCPT`, you have the option to tie them to the same regulator. Decoupling for these pins depends on the design decoupling requirements of the specific board. See Notes 2, 3, 4, and 8.

HPS Dedicated I/O Bank Pins

Table 12. HPS Dedicated I/O Bank Pins
HPS Pin Name	Pin Functions	Pin Description	Connection Guidelines
`HPS_CLK1`	Input, Clock	Dedicated clock input pin that drives the main PLL. This provides clocks to the MPU, L3/L4 sub-systems, debug sub-system and the Flash controllers. It can also be programmed to drive the peripherals.	Connect a single-ended clock source to this pin. The I/O standard of the clock source must be compatible with `VCCIO_HPS`. Refer to the valid frequency range of the clock source in the Intel^® Arria^® 10 Device Datasheet. Unless the `hps_clk_f` fuse is blown, an input clock must be present on this pin for the HPS to boot properly.
`HPS_ nRST`	Bidirectional	Warm reset to the HPS block. Active low bi-directional pin. When driven from the board, the system reset domains that allow debugging to operate are affected. Any cold HPS reset drives the `HPS_nRST` pin low. `HPS_nRST` may be driven low on a warm reset if enabled using the `nrstwarmmask` register in the Reset Manager.	Connect this pin through a 1-kΩ pull-up resistor to `VCCIO_HPS`.
`HPS_ nPOR`	Input	Cold reset to the HPS block. Active low input that resets all HPS logic that can be reset. Places the HPS in a default state sufficient for the software to boot. This pin has an internal 25-kΩ pull-up resistor that is always active.	Connect this pin through a 1–10-kΩ pull-up resistor to `VCCIO_HPS`.

Notes to Intel Arria 10 SX Pin Connection Guidelines

Intel^® provides these guidelines only as recommendations. It is the responsibility of the designer to apply simulation results to the design to verify proper device functionality.

These pin connection guidelines are based on the Intel^® Arria^® 10 SX device variant.
Select the capacitance values for the power supply after you consider the amount of power they need to supply over the frequency of operation of the particular circuit being decoupled. Calculate the target impedance for the power plane based on current draw and voltage drop requirements of the device/supply. Then, decouple the power plane using the appropriate number of capacitors. On-board capacitors do not decouple higher than 100 MHz due to “Equivalent Series Inductance” of the mounting of the packages. Consider proper board design techniques such as interplane capacitance with low inductance for higher frequency decoupling. Refer to the PDN tool.
Use the Intel^® Arria^® 10 Early Power Estimator (EPE) to determine the current requirements for VCC and other power supplies. Use the Intel^® Quartus^® Prime Power Analyzer for the most accurate current requirements for this and other power supplies.
These supplies may share power planes across multiple Intel^® Arria^® 10 devices.
Power pins should not share breakout vias from the BGA. Each ball on the BGA must have its own dedicated breakout via.
Example 8, Example 9, Example 10, Figure 8, Figure 9, and Figure 10 illustrate the power supply sharing guidelines for the Intel^® Arria^® 10 SX devices.
Low Noise Switching Regulator—a switching regulator circuit encapsulated in a thin surface mount package containing the switch controller, power FETs, inductor, and other support components. The switching frequency is usually between 800 kHz and 1 MHz and has fast transient response. The switching frequency range is not an Intel^® requirement. However, Intel^® does require the Line Regulation and Load Regulation meet the following specifications:
- Line Regulation < 0.4%
- Load Regulation < 1.2%
The number of modular I/O banks on Intel^® Arria^® 10 devices depends on the device density. For the indexes available for a specific device, refer to the I/O Bank section in the Intel^® Arria^® 10 Device Handbook.
For AC-coupled links, the AC-coupling capacitor can be placed anywhere along the channel. PCI Express protocol requires that the AC-coupling capacitor is placed on the transmitter side of the interface that permits adapters to be plugged and unplugged.
For item [#], refer to the device pin table for the pin-out mapping.
The peripheral pins are programmable through pin multiplexors. Each pin may have multiple functions. The HPS dedicated I/O pin multiplexing is programmable using the HPS software. The pin mux will determine how the pins are used.
Pin Mux Select 5, 6, 7, 9, 10, 11, and 12 will not assign any HPS dedicated pins to any specific function. Pin Mux Select 5, 6, 7, 9, 10, 11, and 12 are not listed in the HPS Peripheral Pins table.
A warm reset event will not change the configured value of the HPS dedicated I/O Pin Mux.
At cold reset, these pins will default to the GPIO and BSEL functions set.
SD/MMC Power Enable pins are inverted. For details, refer to the Intel^® Arria^® 10 SoC Errata Sheet.
Pin Mux Select 5, 6, 7, 9, 10, and 11 will not assign any HPS dedicated pins to any specific function. Pin Mux Select 5, 6, 7, 9, 10, and 11 are not listed in the Shared 3V I/O Bank Pins table.
A warm reset event will not change the configured value of the HPS shared I/O Pin Mux.
At cold reset, these pins will default to the GPIO function set.
These pins are inverted or active-low signals.
Do not drive the I/O pins externally during the power-up and power-down time to avoid excess current on the I/O pins:
- Excess I/O pin current affects the device's lifetime and reliability.
- Excess current on the 3V I/O pins can damage the Intel^® Arria^® 10 device.
For the acceptable limits on the input current, refer to the Absolute Maximum Ratings section in the Intel^® Arria^® 10 Device Datasheet.

Power Supply Sharing Guidelines for Intel Arria 10 Devices

Example 1— Intel Arria 10 GX

To meet DisplayPort TX electrical full compliance, _{VCCT_GXB} must be 1.03 V or higher. For designs that have high-current for `VCCR_GXB` or `VCCT_GXB`, you should consider the IR drop through the supply planes and compensate for it.
`VCCT_GXB[L,R]`	2	0.95	±30 mV	Switcher (*)	Share
`VCCBAT`	3	Varies	± 5% (**)	Switcher (*)	Share if 1.8V	Option provided for `VCCBAT`, `VCCPT`, `VCCIO`, and `VCCPGM` to share the same regulator when all power rails required 1.8 V. Depending on the regulator capabilities, you have the option to share this supply with multiple Intel^® Arria^® 10 devices.

`VCCIO`		Varies
`VCCPGM`		Varies
`VCCH_GXB[L,R]`		1.8			Isolate	Option provided to share `VCCH_GXB` and `VCCA_PLL` with the same regulator as `VCCBAT`, `VCCPT`, `VCCIO`, and `VCCPGM` when all power rails require 1.8 V with a proper isolation filter.
`VCCA_PLL`		1.8			Isolate

(*)When using a switcher to supply these voltages, the switcher must be a low noise switcher as defined in note 7 of the Notes to Intel^® Arria^® 10 GX and GT Pin Connection Guidelines.

(**)The supported tolerance for the V_CCIO power supply varies depending on the I/O standards. For more details, refer to the I/O standard specification in the Intel^® Arria^® 10 Device Datasheet. Use the EPE (Early Power Estimation) tool to assist in determining the power required for your specific design.

Each board design requires its own power analysis to determine the required power regulators needed to satisfy the specific board design requirements. An example block diagram using the Intel^® Arria^® 10 GX device is provided in Figure 1.
