® Data Sheet X9C102, X9C103, X9C104, X9C503 July 20, 2009 FN8222.3 Digitally Controlled Potentiometer (XDCP™) The X9C102, X9C103, X9C104, X9C503 are Intersils’ digitally controlled (XDCP) potentiometers. The device consists of a resistor array, wiper switches, a control section, and non-volatile memory. The wiper position is controlled by a three-wire interface. The potentiometer is implemented by a resistor array composed of 99 resistive elements and a wiper switching network. Between each element and at either end are tap points accessible to the wiper terminal. The position of the wiper element is controlled by the CS, U/D, and INC inputs. The position of the wiper can be stored in non-volatile memory and then be recalled upon a subsequent power-up operation.
