M62021L - System Reset-IC
The M62021 is a system IC that controls the memory backup function of 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,
M62021L Features
* Built-in switch for selection between main power supply and backup power supply to RAM.
* Small difference between input and output voltage (IOUT = 80 mA, VIN = 5 V) 0.2 V Typ
* Detection voltage (power supply monitor voltage) 4.40 V ± 0.2 V
* Chip select signal out
