1.4.1. HPS Power Supply Pins
Pin Name | Pin Functions | Pin Description | Connection Guidelines |
---|---|---|---|
VCCL_HPS | Power | VCCL_HPS supplies power to the HPS DSU and periphery circuitry. | For the range of the VCCL_HPS power supply voltage, refer to the Agilex™ 5 FPGAs and SoCs Device Data Sheet . Altera recommends you share VCCL_HPS with VCC together. If you do not intend to utilize the HPS in the Agilex™ 5 device, you must still provide power to the HPS power supply. Do not leave the VCCL_HPS floating or connected to GND. |
VCCL_HPS_CORE0_CORE1 | Power | Supply power to HPS A55 Core 0 and Core 1. | For the range of the VCCL_HPS_CORE0_CORE1 power supply voltage, refer to the Agilex™ 5 FPGAs and SoCs Device Data Sheet . VCCL_HPS_CORE0_CORE1 must be sourced from the same regulator with VCCL_HPS. Altera recommends you share this power with VCC together. You have the option to connect this pin to GND if you do not intend to use the Cortex* -A55 cores. |
VCCL_HPS_CORE2 | Power | Supply power to the HPS A76 Core 2. | For the range of the VCCL_HPS_CORE2 power supply voltage, refer to the Agilex™ 5 FPGAs and SoCs Device Data Sheet . VCCL_HPS_CORE2 must be sourced from the same regulator with VCCL_HPS. Altera recommends you share this power with VCC together. You have the option to connect this pin to GND if you do not intend to use the Cortex* -A76 core 2. |
VCCL_HPS_CORE3 | Power | Supply power to the HPS A76 Core 3. | For the range of the VCCL_HPS_CORE3 power supply voltage, refer to the Agilex™ 5 FPGAs and SoCs Device Data Sheet . VCCL_HPS_CORE3 must be sourced from the same regulator with VCCL_HPS. Altera recommends you share this power with VCC together. You have the option to connect this pin to GND if you do not intend to use the Cortex* -A76 core 3. |
VCCIO_HPS | Power | The HPS dedicated I/Os support 1.8-V voltage level. | Connect these pins to 1.8-V power supply. You have the option to source VCCIO_HPS pins from the same regulator as VCCPT. If you do not intend to utilize the HPS in the Agilex™ 5 device, you must still provide power to the HPS power supply. Do not leave the VCCIO_HPS floating or connected to GND. |
VCCPLL1_HPS | Power | Supply analog power to the main HPS PLLs. | Connect these pins to a 1.8-V power supply. You have the option to share VCCPLL1_HPS with the same regulator as VCCPLL_SDM. If you do not intend to utilize the HPS in the Agilex™ 5 device, you must still provide power to the HPS power supply. Do not leave the VCCPLL1_HPS floating or connected to GND. |
VCCPLL2_HPS | Power | Supply analog power to the peripheral HPS PLLs. | Connect these pins to a 1.8-V power supply. You have the option to share VCCPLL2_HPS with the same regulator as VCCPLL_SDM. If you do not intend to utilize the HPS in the Agilex™ 5 device, you must still provide power to the HPS power supply. Do not leave the VCCPLL2_HPS floating or connected to GND. |
VCCPLLDIG1_HPS | Power | Digital power supply of the main HPS PLLs. | Connect this to the VCCL_HPS with proper isolation filtering. If you do not intend to utilize the HPS in the Agilex™ 5 device, you must still provide power to the HPS power supply. Do not leave the VCCPLLDIG1_HPS floating or connected to GND. |
VCCPLLDIG2_HPS | Power | Digital power supply of the peripheral HPS PLLs. | Connect this to the VCCL_HPS with proper isolation filtering. If you do not intend to utilize the HPS in the Agilex™ 5 device, you must still provide power to the HPS power supply. Do not leave the VCCPLLDIG2_HPS floating or connected to GND. |
