The M62021 is a system IC that controls the memory backup function of SRAM and microcomputer (internal RAM).
The IC outputs reset signals(RES/RES) to a microcomputer 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 microcomputer
system,so that the IC makes it possible to construct a system easily and with fewer components compared with a
conventional case that uses individual ICs and discrete components.
