I was wondering if the SRAM by CY62177EV30 is compatible with the FMC on STM32L496AEI with 20 bit address width and 16 bit data width.
I can only use 20 bits from the address bus because of pin multiplexing constraints. There are 21 address pins on the SRAM I want to use so I am also unsure what to do with that. Is it okay not to connect that on SRAM? (I am aware this will result in halving of the total capacity of the SRAM)
