CAT1161, CAT1162  
Supervisory Circuits with  
I2C Serial CMOS EEPROM,  
Precision Reset Controller  
and Watchdog Timer (16K)  
http://onsemi.com  
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  
2
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.
