Supervisory Circuits with

I²C Serial CMOS EEPROM,

Precision Reset Controller

and Watchdog Timer (16K)

Description

The CAT1161/2 is a complete memory and supervisory solution for

microcontroller−based systems. A serial EEPROM memory (16K)

with hardware memory write protection, a system power supervisor

with brown out protection and a watchdog timer are integrated

together in low power CMOS technology. Memory interface is via an

PDIP−8

CASE 646AA

SOIC−8

CASE 751BD

I C bus.

The 1.6−second watchdog circuit returns a system to a known good

state if a software or hardware glitch halts or “hangs” the system. The

CAT1161 watchdog monitors the SDA line, making an additional PC

board trace unnecessary. The lower cost CAT1162 does not have a

watchdog timer.

The power supply monitor and reset circuit protects memory and

system controllers during power up/down and against brownout

conditions. Five reset threshold voltages support 5 V, 3.3 V and 3 V

systems. If power supply voltages are out of tolerance reset signals

become active, preventing the system microcontroller, ASIC or

peripherals from operating. Reset signals become inactive typically

200 ms after the supply voltage exceeds the reset threshold level. With

both active high and low reset signals, interface to microcontrollers

and other ICs is simple. In addition, a reset pin can be used as a

debounced input for pushbutton manual reset capability.
