Notes: 1.Applicable for standalone VCCINT or combined VCCINT/VCCINT_IO/VCCBRAM. The capacitors listed are the total number of capacitors for each scenario. 2.Combine VCCBRAM and VCCINT_IO when not at same voltage as VCCINT. The capacitors listed are the total number of capacitors for the combined rail. 3.VCCAUX and VCCAUX_IO must share the same plane on the PCB. The capacitors listed are the total number of capacitors for the combined rail. 4.The 22 µF capacitor can be combined at one per every four shared HRIO/HPIO banks. |
