Low Power 2 Output System Reset IC

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.

•
Two-step detection of supply voltage
Detection voltage in normal mode: V
S
= 2.7 V (Typ)
Detection voltage in backup mode: V
BATT
= 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.
