1.8.1. Example 1— Intel® Agilex™ Devices (P-Tile and E-Tile)
Power Pin Name | Regulator Group | Voltage Level (V) | Supply Tolerance | Power Source | Regulator Sharing | Notes |
---|---|---|---|---|---|---|
VCC | 1 | SmartVID1, 0.8 | ± 3% | Switcher 2 | Share | Source VCC and VCCP from the same regulator, sharing the same voltage plane. You have the option to connect VCCL_HPS to the same regulator as VCC and VCCP when the power rails require the same voltage level. You may also connect the VCCPLLDIG_HPS power to the shared VCC, VCCP, and VCCL_HPS power planes with proper isolation filtering. For -4X devices, VCC and VCCP are powered by SmartVID and a separate fixed 0.8V supply must be used for VCCL_HPS and filtered VCCPLLDIG_HPS. When implementing a filtered supply topology, you must consider the IR drop across the filter. If you do not intend to utilize the HPS in the Intel® Agilex™ device, you must still provide power to these power supply pins. Do not leave the VCCL_HPS and VCCPLLDIG_HPS power supply pins floating or connected to GND. |

VCCPT | 6 | 1.8 | ± 3% | Switcher2 | Share | Connect VCCPT to a dedicated 1.8-V power supply. Connect VCCADC, VCCPLL_SDM, VCCPLL_HPS, and VCCCLK_GXP to the same power plane with proper isolation filtering. Depending on the regulator capabilities, you have the option to share this supply with multiple Intel® Agilex™ devices. If you do not intend to utilize the HPS in the Intel® Agilex™ device, you must still provide power to the HPS power supply pins. When implementing a filtered supply topology, you must consider the IR drop across the filter. |

Do not leave the VCCIO_HPS power supply pins floating or connected to GND. |

VCCFUSEWR_SDM | 9 | 1.8 | ± 50 mV | Switcher2 | Isolate | A 1.8-V power supply is required on this pin if field-programming of the eFuses is required. If field-programming of the eFuses is not required, tie this pin to VCCPT or leave it unconnected (floating). Do not tie this pin to GND. If field-programming of the eFuses is required, Intel® recommends using an adjustable regulator set to 1.8-V output when programming the eFuses. |
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® Agilex™ device is provided in Figure 1.
