DESCRIPTION  
CPU Supervisor  
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.  
FEATURES  
• Selectable watchdog timer  
—Select 200ms, 600ms, 1.4s, off  
• Low V detection and reset assertion  
CC  
—Five standard reset threshold voltages  
nominal 4.62V, 4.38V, 2.92V, 2.68V, 1.75V  
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.  
—Adjust low V reset threshold voltage using  
CC  
special programming sequence  
—Reset signal valid to V = 1V  
CC  
• Low power CMOS  
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.  
—12µA typical standby current, watchdog on  
—800nA typical standby current watchdog off  
—3mA active current  
2
• 400kHz I C interface  
• 1.8V to 5.5V power supply operation  
• Available packages  
—8-lead SOIC  
The device’s low V  
detection circuitry protects the  
CC  
—8-lead MSOP  
user’s system from low voltage conditions, resetting the  
system when V falls below the minimum V trip  
CC  
CC  
point. RESET/RESET is asserted until V  
returns to  
CC  
proper operating level and stabilizes. Five industry stan-  
dard V thresholds are available; however, Intersil’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.
