Description

Electronic Component Model: X5045S8IZ-

The X5045S8IZ is a CPU Supervisor with 4K SPI EEPROM. It combines four popular functions, including Power-on Reset Control, Watchdog Timer, Supply Voltage Supervision, and Block Lock Protect Serial EEPROM Memory, in one package. This combination not only lowers system cost but also reduces board space requirements and increases reliability.

Specifications and features
