Description
The M62001 to M62008 are semiconductor integrated circuits whose optimum use is for the detection of the rise and
fall in the power supply to a microcomputer system in order to reset or release the microcomputer system.
The M62001 to M62008 carry out voltage detection in two-steps and have two output pins. As Bi-CMOS process and
low power dissipating circuits are employed, they output optimum signals through each output pin to a system that
requires RAM backup. As output signals, interruption (INT) and compulsive reset (RESET) signals are available. The
interruption signal (INT) is used to alter the microcomputer from normal mode to backup mode and vice versa. These
output signals are classified into pulse type (M62001 to M62004) and hold type (M62005 to M62008).
Features
Bi-CMOS process realizes a configuration of low current dissipating circuits.

Application
Prevention of errors in microcomputer system in electronic equipment that requires RAM backup, such as office,
industrial, and home-use equipment.
