Notes:
1. Dynamic power consumption is given for standard load and software default drive strength and output slew.
2. PDC3 is the static power (where applicable) measured on VCCI.
3. PAC10 is the total dynamic power measured on VCC and VCCI.
4. All LVCMOS 3.3 V software macros support LVCMOS 3.3 V wide range as specified in the JESD8-B specification.

Note: For a different output load, drive strength, or slew rate, Microsemi recommends using the Microsemi power
calculator or SmartPower in Libero SoC.
