PIN (SOIC/PDIP) 1 PIN TSSOP 1 NAME CS FUNCTION Chip Select Input.

CS HIGH, deselects the device and the SO output pin is at a high impedance state.

Unless a nonvolatile write cycle is underway, the device will be in the standby power mode.

CS LOW enables the device, placing it in the active power mo

® 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.
