CPU Supervisor with 64K EEPROM  
DESCRIPTION  
FEATURES  
• Selectable watchdog timer  
The X4643/5 combines four popular functions, Power-on  
Reset Control, Watchdog Timer, Supply Voltage  
Supervision, and Serial EEPROM Memory in one  
package. This combination lowers system cost,  
reduces board space requirements, and increases reli-  
ability.  
• Low V  
detection and reset assertion  
CC  
—Four standard reset threshold voltages  
—Adjust low V reset threshold voltage using  
CC  
special programming sequence  
—Reset signal valid to V = 1V  
CC  
• Low power CMOS  
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.  
—<20µA max standby current, watchdog on  
—<1µA standby current, watchdog off  
—3mA active current  
• 64Kbits of EEPROM  
—64-byte page write mode  
—Self-timed write cycle  
—5ms write cycle time (typical)  
• Built-in inadvertent write protection  
—Power-up/power-down protection circuitry  
• 400kHz 2-wire interface  
• 2.7V to 5.5V power supply operation  
• Available packages  
—8-lead SOIC  
The Watchdog Timer provides an independent protection  
mechanism for microcontrollers. When the microcon-  
troller fails to restart a timer within a selectable 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.  
The device’s low V  
detection circuitry protects the  
CC  
user’s system from low voltage conditions, resetting the  
system when V falls below the set minimum V trip
