DESCRIPTION  
CPU Supervisor  
This device combines three popular functions, Power-  
on Reset, Watchdog Timer, and Supply Voltage  
Supervision in one package. This combination lowers  
system cost, reduces board space requirements, and  
increases reliability.  
FEATURES  
• 200ms power-on reset delay  
• Low V detection and reset assertion  
CC  
—Five standard reset threshold voltages  
—Adjust low V reset threshold voltage using  
CC  
The watchdog timer provides an independent protec-  
tion mechanism for microcontrollers. During a system  
failure, the device will respond with a RESET signal  
after a selectable time out interval. The user selects the  
interval from three preset values. Once selected, the  
interval does not change, even after cycling the power.  
special programming sequence  
—Reset signal valid to V = 1V  
CC  
• Selectable nonvolatile watchdog timer  
—0.2, 0.6, 1.4 seconds  
—Off selection  
—Select settings through software  
• Long battery life with low power consumption  
—<50µA max standby current, watchdog on  
—<1µA max standby current, watchdog off  
• 2.7V to 5.5V operation  
The user’s system is protected from low voltage condi-  
tions by the device’s low V detection circuitry. When  
CC  
V
falls below the minimum V trip point, the system  
CC  
CC  
is reset. RESET is asserted until V returns to proper  
CC  
• SPI mode 0 interface  
operating levels and stabilizes. Five industry standard  
• Built-in inadvertent write protection  
—Power-up/power-down protection circuitry  
—Watchdog change latch  
• High reliability  
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.  
• Available packages  
—8-lead TSSOP  
—8-lead SOIC  
—8 pin PDIP  
The device utilizes Intersil’s proprietary Direct Write  
cell for the watchdog timer control bits and the V  
TRIP  
storage element, providing a minimum endurance of  
100,000 write cycles and a minimum data retention of  
100 years.
