Can I switch SRAM from another brand w/ Renesas’ SRAM w/o changing PCB?

Latest Updated:03/16/2012


Can I replace SRAM from a different manufacturer with Renesas’ SRAM without having to change the PCB, even if the address pin number of SRAM of Renesas and the other manufacturer differ?


Each manufacturer can number their address pins arbitrarily.
As SRAM function is full random access memory, users don’t have tocare about a pin's numbering, such as A0 or A1. Because users assign one address and select one memory cell, users can write/read data onthe assigned address and corresponding memory cell. So even if the address pin name is different, the device will work properly.
