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.
Typical Application |
Features |
| Power supply control systems for memory backup of microcomputer system and SRAM boards with built-in backup function that require switching between external power supply and battery. | •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 typ•Detection voltage (power supply monitor voltage)4.40V±0.2V•Chip select signal output(CS) Two channels of reset outputs(RES/RES)•Power on reset circuit built-in•Delay time variable by an external capacitance connected to Ct pin•Facilitates to form backup function with a few number of components |
