Product Summary

The X5045S8IZ-2.7T1 is a CPU Supervisor with 4Kbit SPI EEPROM. It combines four popular functions, Poweron Reset Control, Watchdog Timer, Supply Voltage Supervision, and Block Lock Protect Serial EEPROM Memory in one package. This combination lowers system cost, reduces board space requirements, and increases reliability. Applying power to the X5045S8IZ-2.7T1 activates the power-on reset circuit which holds RESET/RESET active for a period of time. This allows the power supply and oscillator to stabilize before the processor can execute code.
