M62021 back-up equivalent, system reset ic with switch for memory back-up.
*Built-in switch for selection between main power supply and backup power supply to RAM.
*Small difference between input and output voltage (IOUT=80mA,VIN=5V)0.2V.
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 .
