® X5168, X5169 (Replaces X25268, X25169) Data Sheet June 15, 2006 FN8130.
2 CPU Supervisor with 16Kbit SPI EEPROM These devices combine three popular functions, Power-on Reset Control, 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 device 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.
The device’s low VCC detection circuitry protects the user’s system from low voltage conditions by holding RESET/...
