Digitally Controlled Potentiometer
(XDCP™)
The Intersil X9317 is a digitally controlled potentiometer
(XDCP™). The device consists of a resistor array, wiper
switches, a control section, and nonvolatile memory. The
wiper position is controlled by a 3-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 nonvolatile
memory and then be recalled upon a subsequent power-up
operation.
The device can be used as a three-terminal potentiometer
for voltage control or as a two-terminal variable resistor for
current control in a wide variety of applications.

BRIEF DESCRIPTION
Increment.
Toggling INC while CS is low moves the wiper either up or down.
Up/Down.
The U/D input controls the direction of the wiper movement.
The high terminal is equivalent to one of the fixed terminals of a mechanical potentiometer.
Ground.
The wiper terminal is equivalent to the movable terminal of a mechanical potentiometer.
The low terminal is equivalent to one of the fixed terminals of a mechanical potentiometer.
Chip Select.
The device is selected when the CS input is LOW, and de-selected when CS is
high.
Supply Voltage.
