X40431 Overview
The X40430, X40431, X40434, X40435 bines power-on reset control, watchdog timer, supply voltage supervision, second 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...
