CPU Supervisor with 64Kbit SPI EEPROM

FEATURES  
DESCRIPTION  
• Low V detection and reset assertion  
—Five standard reset threshold voltages  
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.  
CC  
—Re-program low V reset threshold voltage  
CC  
using special programming sequence  
—Reset signal valid to V = 1V  
CC  
• 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  
• 64Kbits of EEPROM  
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.  
• Built-in inadvertent write protection  
—Power-up/power-down protection circuitry  
—Protect 0, 1/4, 1/2 or all of EEPROM array with  
The device’s low V  
user’s system from low voltage conditions by holding  
RESET/RESET active when V falls below a minimum  
detection circuitry protects the

trip point. RESET/RESET remains asserted until  
returns to proper operating level and stabilizes. Five  
CC  
—In circuit programmable ROM mode  
• 2MHz SPI interface modes (0,0 & 1,1)  
• Minimize EEPROM programming time  
—32-byte page write mode

industry standard V  
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.  
—Self-timed write cycle  
—5ms write cycle time (typical)  
• 2.7V to 5.5V and 4.5V to 5.5V power supply
