CPU Supervisor  
FEATURES  
DESCRIPTION  
• Selectable watchdog timer  
—Select 200ms, 600ms, 1.4s, off  
These devices combine three popular functions, Power-  
on Reset Control, Watchdog Timer, and Supply Voltage  
Supervision. This combination lowers system cost,  
reduces board space requirements, and increases  
reliability.  
• Low V  
detection and reset assertion  
CC  
—Five standard reset threshold voltages  
nominal 4.62V, 4.38V, 2.92V, 2.68V, 1.75V  
—Adjust low V  
special programming sequence  
—Reset signal valid to V = 1V  
reset threshold voltage using  
CC  
Applying power to the device activates the power on  
reset circuit which holds RESET/RESET active for a  
period of time. This allows the power supply and oscilla-  
tor to stabilize before the processor can execute code.  
CC  
• Low power CMOS  
—12µA typical standby current, watchdog on  
—800nA typical standby current watchdog off  
—3mA active current  
The Watchdog Timer provides an independent  
protection mechanism for microcontrollers. When the  
microcontroller fails to restart a timer within a select-  
able time out interval, the device activates the RESET/  
RESET signal. The user selects the interval from three  
preset values. Once selected, the interval does not  
change, even after cycling the power.  
• 400kHz I2C interface  
• 1.8V to 5.5V power supply operation  
• Available packages  
—8-lead SOIC  
—8-lead MSOP  
The device’s low V  
detection circuitry protects the  
CC  
user’s system from low voltage conditions, resetting the  
system when V falls below the minimum V trip  
CC  
CC  
returns to  
point. RESET/RESET is asserted until V  
CC  
proper operating level and stabilizes. Five industry stan-  
dard V thresholds are available; however, Xicor’s  
TRIP  
unique circuits allow the threshold to be reprogrammed  
to meet custom requirements, or to fine-tune the thresh-  
old for applications requiring higher precision.
