Resolved! STM32H7 with Muxed PSRAM role of Byte Enable pins and compatibility with ISSI parts
IS61WV25616MEBLL and IS64WV25616MEBLL are recent Muxed PSRAM from ISSI. I would like to use these with an LQFN100 STM32H750VBTx to avoid complicated routing with SRAM and going to a larger LQFN or BGA package.The FMC of this MCU supports Muxed PSRAM....
