Programming Spartan7 with S25FL512S

[485337]

HI.

I want try program Spartan7 (all banks tied to 2.5V) with SPI Spansion S25FL512S (part number - S25FL512SAGMFIR10). S25FL512S supports:

I want connect Core supply to 3.3V and IO supply to 2.5V. Is it correct to provide programming in this configuration?

according to the flash datasheet, the I/O's can range from 1.65 to Vcc.

Since you want to use at 2.5v interface for fpga IO's, you are ok to select the Vio to 2.5v.

make sure you follow the configuration guide to check if you followed the recommendations.

CFGBVS needs to be connected to Vcco.
