Posted on June 05, 2017 at 07:27Hi all!
We're working on a board that uses the STM32F7 and we'd like to add external SRAM and NOR Flash. In both cases, we'd like to use Serial memory to save on IO pins, layout, etc.
In looking at the schematics for the STF32F779I-EVAL board, I see that they've added SRAM, NOR FLASH, and SDRAM, but in all three cases they're parallel versions, rather than serial.
Is this possible? Can they both be wired to the FMC using the QSPI interface?
For reference,
https://www.digikey.com/product-detail/en/issi-integrated-silicon-solution-inc/IS25LP128-JLLE/706-1342-ND/5189777
is the NOR FLASH we'd like to use, and

is the SRAM.
Thanks!
