Latest Updated:03/16/2012


For SRAM that has two chip select pins, CS1# and CS2, and SRAM is being controlled using one of them, how should the unused chip select pin be dealt with?


When not using CS1# pin, please connect CS2 to Vss of SRAM.
When not using CS2, please connect CS1# toVcc of SRAM.
