Notes:
1.
VCCINT, VCCAUX, and VCCO supplies to the FPGA can be applied in any order. However, the FPGA’s configuration source (SPI Flash, parallel
NOR Flash, microcontroller) might have specific requirements. Check the data sheet for the attached configuration source. Apply VCCINT last
for lowest overall power consumption (see UG331 chapter "Powering Spartan-3 Generation FPGAs" for more information).
2.
To ensure successful power-on, VCCINT, VCCO Bank 2, and VCCAUX supplies must rise through their respective threshold-voltage ranges with
no dips at any point.
