Notes:
1.
VCCINT, VCCAUX, and VCCO supplies to the FPGA can be applied in any order. However, the FPGA’s configuration source (Platform Flash,
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.
