M62023P

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.

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 M62023L/P/FP 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.
