M62023P Overview
The M62023L/P/FP is a system reset IC that controls the memory backup function of an SRAM and an embedded RAM of a microcontroller. The IC outputs reset signals (RES/RES) to a microcontroller at power-down and power failure. It also shifts the power supply to RAMs from main to backup, outputs a signal (CS) that invokes standby mode, and alters RAMs to backup circuit mode.
M62023P Key Features
- Built-in switch for selection between main power supply and backup power supply to RAMs
- Small difference between input and output voltages (IOUT=80mA, VIN=3V) : 0.15V typ
- Detection voltage (power supply monitor voltage) : 2.57V typ
- Chip select signal output (CS)
- Two channels of reset outputs (RES/RES)
- Power on reset circuit
