PRELIMINARY
Some parametric limits are subject to change.
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
(I

=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.
