Description

The M62015 and M62016 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 M62015 and M62016 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.

These ICs also support the backup mode of Renesas microcomputer the M16C.

Features

? Bi-CMOS process realizes a configuration of low current dissipating circuits.

Circuit current

ICC = 3 μA (Typ, normal mode, VCC = 3.0 V)

ICC = 1 μA (Typ, backup mode, VCC = 2.5 V)

? Two-step detection of supply voltage

Detection voltage in normal mode: VS = 2.7 V (Typ)

Detection voltage in backup mode: VBATT = 2.0 V (Typ)

? Two outputs

Reset output (RESET): output of compulsive reset signal

Interruption output (INT): output of interruption signal

? Two types of output forms

CMOS output: M62015L/FP

open drain output: M62016L/FP

Application

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