8K x 8 Bit  
X40626  
Dual Voltage CPU Supervisor with 64K Serial EEPROM  
FEATURES  
DESCRIPTION  
• Dual voltage monitoring  
The X40626 combines four popular functions, Power-on  
Reset Control, Watchdog Timer, Dual Supply Voltage  
Supervision, and Serial EEPROM Memory in one pack-  
age. This combination lowers system cost, reduces  
board space requirements, and increases reliability.  
—V operates independent of V  
2Mon  
CC  
• Watchdog timer with selectable timeout intervals  
• Low V detection and reset assertion  
CC  
—Four standard reset threshold voltages  
—User programmable V threshold  
TRIP  
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 stabi-  
lize before the processor can execute code.  
—Reset signal valid to V =1V  
CC  
• Low power CMOS  
—20µA max standby current, watchdog on  
—1µA standby current, watchdog OFF  
• 64Kbits of EEPROM  
The Watchdog Timer provides an independent protection  
mechanism for microcontrollers. When the microcontrol-  
ler 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.  
—64 byte page size  
• Built-in inadvertent write protection  
—Power-up/power-down protection circuitry  
—Protect 0, 1/4, 1/2, all or 64, 128, 256 or 512  
bytes of EEPROM array with programmable  
Block Lock™ protection  
• 400kHz 2-wire interface  
—Slave addressing supports up to 4 devices on  
the same bus  
• 2.7V to 5.5V power supply operation  
• Available Packages  
—14-lead SOIC  
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

point. RESET is asserted until V  
returns to proper
