Data Sheet  
September 16, 2005  
FN8130.1  
CPU Supervisor with 16Kbit SPI EEPROM  
Features  
• Low VCC Detection and Reset Assertion  
- Five standard reset threshold voltages  
- Re-program low VCC reset threshold voltage using  
special programming sequence  
These devices combine three popular functions, Power-on  
Reset Control, Supply Voltage Supervision, and Block Lock  
Protect 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/RESET active for a period of  
time. This allows the power supply and oscillator to stabilize  
before the processor can execute code.  
• 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 device’s low VCC detection circuitry protects the user’s  
system from low voltage conditions by holding  
• 16Kbits of EEPROM  
• Built-in Inadvertent Write Protection  
RESET/RESET active when VCC falls below a minimum VCC  
trip point. RESET/RESET remains asserted until VCC returns  
to 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 in  
applications requiring higher precision.  
- Power-up/power-down protection circuitry  
- Protect 0, 1/4, 1/2 or all of EEPROM array with Block  
Lock™ protection  
- In circuit programmable ROM mode  
• 2MHz SPI Interface Modes (0,0 & 1,1)  
• Minimize EEPROM Programming Time  
- 32-byte page write mode  
- Self-timed write cycle  
- 5ms write cycle time (typical)  
• 2.7V to 5.5V and 4.5V to 5.5V Power Supply  
Operation  
• Available Packages  
- 14 Ld TSSOP, 8 Ld SOIC, 8 Ld PDIP  
• Pb-Free Plus Anneal Available (RoHS Compliant)
