X5329 Overview
These devices bine three popular functions, Poweron Reset Control, Supply Voltage Supervision, and Block Lock Protect Serial EEPROM Memory in one package. This bination lowers system cost, reduces board space requirements, and increases reliability. Applying power to the device activates the power-on reset circuit which holds RESET/RESET active for a period of time.
