MITSUBISHI<Dig.Ana.INTERFACE> M62021L,P,FP SYSTEM RESET IC WITH SWITCH FOR MEMORY BACK-UP DESCRIPTION The M62021 is a system IC that controls the memory backup function of SRAM and microputer (internal RAM). The IC outputs reset signals(RES/RES) to a microputer at power-down and power failure.It also shifts the power supply to RAM from main to backup,outputs a signal (CS) that invokes standby mode,and alters RAM to backup circuit mode. The M62021 contains,in a single chip,power supply monitor and RAM backup functions needed for a microputer system,so that the IC makes it possible to construct a system easily and with fewer ponents pared with a conventional case that uses...
