DESCRIPTION

The M62001~8 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 M62001~8 carry out voltage detection in 2 steps and have 2 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~M62004) and hold type (M62005~M62008).
