Product Summary
The X5645P is a CPU Supervisor with 64Kbit 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 X5645P 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.
Parametrics
X5645P absolute maximum ratings: (1)Temperature under bias: -65℃ to +135℃; (2)Storage temperature: -65℃ to +150℃; (3)Voltage on any pin with respect to VSS: -1.0V to +7V; (4)D.C. output current: 5mA; (5)Lead temperature (soldering, 10 seconds): 300℃.
