mP Supervisory Circuit  
General Description  
Features  
Power OK/Reset Time Delay, 250ms min.  
Watchdog Timer, 150ms, 600ms, or 1.2s typical  
Precision Supply Voltage Monitor, Select Between 5% or  
10% of Supply Voltage  
The ILC1232 is a multifunction circuit which monitors micro-  
processor activity, external reset and power supplies in  
microprocessor based systems. The circuit functions  
include a watchdog timer, power supply monitor, micro-  
processor reset, and manual pushbutton reset input.  
18µA Supply Current  
Debounced External Reset Input  
8-Pin SO Package  
The power supply line is monitored with a comparator and  
an internal voltage reference. RST is forced low when an  
out-of-tolerance condition exists and remains asserted for  
at least 250ms after VCC rises above the threshold voltage  
Applications  
Computers  
Controllers  
(4.5V or 4.75V). The RST pin will remain logic low with VCC  
as low as 1.4V.  
Critical Microprocessor Power Monitoring  
Intelligent Instruments  
Portable Equipment  
The Watchdog input (ST) monitors mP activity and will  
assert RST if no mP activity has occurred within the watch-  
dog timeout period. The watchdog timeout period is selec-  
table with nominal periods of 150, 600, or 1200 milliseconds.
