Product Summary
The X4645S8I-2.7 is a CPU Supervisor with 64K EEPROM. The X4645S8I-2.7 combines four popular functions, Power-on Reset Control, Watchdog Timer, Supply Voltage Supervision, and Serial EEPROM Memory in one package. This combination lowers system cost, reduces board space requirements, and increases reliability. Applying power to the X4645S8I-2.7 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.
