Preliminary Information 4kbit EEPROM
X40430/X40431
DESCRIPTION The X40430/31 combines 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 combination 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 b...
