X5168 CPU Supervisor with 16Kbit SPI EEPROM

The X5168,X5169 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/RESET active when VCC falls below a minimum VCC trip point. RESET/RESET remains asserted until VCC returns to proper operating level and stabilizes. Five industry standard VTRIP thresholds are available, however, Intersil's unique circuits allow the threshold to be reprogrammed to meet custom requirements or to fine-tune the threshold in applications requiring higher precision
