SPI flash and power supply
on schematic of the FX3 Board Device REV3, sheet 5, i see that VCC pin of SPI flash is connected to VIO4. Now, flash connected there ( and those that are suggested in datasheet ) are all graded for 2.3-3.6V power supply. However VIO4 can also be connected to 1.8V.
My question is can i use a flash that is rated for 1.8V power supply?
