Preliminary Information 4kbit EEPROM X40430/X40431 DESCRIPTION The X40430/31 bines power-on reset control, watchdog timer, supply voltage supervision, secondary and third voltage supervision, manual reset, and Block Lock™ protect serial EEPROM in one package. This bination lowers system cost, reduces board space requirements, and increases reliability. Applying voltage to VCC activates the power on reset circuit which holds RESET/RESET active for a period of time. This allows the power supply and system oscillator to stabilize before the processor can execute code. Low VCC detection circuitry protects the user’s system from low voltage conditions, resetting the system when VCC falls...
