Digitally Controlled Potentiometer
(XDCP™)
Features
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.
• Three-Wire Serial 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.
