GENERAL DESCRIPTION
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.

FEATURES
• Built-in switch for selection between main power supply and back up 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

APPLICATION
  Power supply control systems for memory of microcontroller systems in electronic equipment such as OA equipment, industrial equipment, and home-use electronic appliances and SRAM boards with built-in backup function that require switching between external power supply and battery.
