Xicor X40431
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. This allows the power supply and system oscillator to stabilize before the processor can execute code.

DESCRIPTION
Applying voltage to VCC activates the power on reset circuit which holds RESET/RESET active for a period of time. Low VCC detection circuitry protects the user’s system from low voltage conditions, resetting the system when VCC falls below the minimum VTRIP1 point. RESET/ RESET is active until VCC returns to proper operating level and stabilizes. A second and third voltage monitor circuit tracks the unregulated supply to provide a power fail warning or monitors different power supply voltage. Three common low voltage combinations are available, however, Xicor’s unique circuits allows the threshold for either voltage monitor to be reprogrammed to meet special needs or to fine-tune the threshold for applications requiring higher precision.
