HPS Supply 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.

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.
