X40434 Overview
Description
The X40430, X40431, X40434, X40435 combines 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 combination lowers system cost, reduces board space requirements, and increases reliability.
