FN8127.2  
CPU Supervisor with 8Kbit SPI EEPROM  
Features  
• Low VCC detection and reset assertion  
- Four standard reset threshold voltages  
4.63V, 4.38V, 2.93V, 2.63V  
- Re-program low VCC reset threshold voltage using  
special programming sequence  
This device combines four popular functions, Power-on Reset  
Control, Watchdog Timer, Supply Voltage Supervision, and  
Block Lock Serial EEPROM Memory in one package. This  
combination lowers system cost, reduces board space  
requirements, and increases reliability.  
- Reset signal valid to VCC = 1V  
Applying power to the device activates the power-on reset  
circuit which holds RESET active for a period of time. This  
allows the power supply and oscillator to stabilize before the  
processor can execute code.  
• Selectable time out watchdog timer  
• Long battery life with low power consumption  
- <50µA max standby current, watchdog on  
- <1µA max standby current, watchdog off  
- <400µA max active current during read  
The Watchdog Timer provides an independent protection  
mechanism for microcontrollers. When the microcontroller fails to  
restart a timer within a selectable time out interval, the device  
activates the RESET signal. The user selects the interval  
from three preset values. Once selected, the interval does  
not change, even after cycling the power.  
• 8Kbits of EEPROM  
• Save critical data with Block Lockmemory  
- Block lock first or last page, any 1/4 or lower 1/2 of  
EEPROM array  
The device’s low VCC detection circuitry protects the user’s  
system from low voltage conditions, resetting the system  
when VCC falls below the minimum VCC trip point. RESET is  
asserted until VCC returns to the proper operating level and  
stabilizes. Five industry standard VTRIP thresholds are  
available, however, Intersil’s unique circuits allow the threshold  
to be reprogrammed to meet custom requirements or to fine-  
tune the threshold for applications requiring higher precision.  
• Built-in inadvertent write protection  
- Write enable latch  
- Write protect pin  
• SPI Interface - 3.3MHz clock rate  
• Minimize programming time  
- 16 byte page write mode  
- 5ms write cycle time (typical)  
Pinouts  
• SPI modes (0,0 & 1,1)
