SYSTEM RESET IC WITH SWITCH FOR MEMORY BACK-UP
DESCRIPTION
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.
FEATURES
Built-in switch for selection between main power supply and
backup power supply to RAM.
Small difference between input and output voltage
(I
OUT
=80mA,V

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

APPLICATION
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.
