Digitally Controlled Potentiometer
(XDCP™)
The Intersil X9315 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 31 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 or
as a two-terminal variable resistor in a wide variety of
applications including:
• Control
• Parameter Adjustments
• Signal Processing

changed by the system or until a power-up/down cycle
recalled the previously stored data.
This procedure allows the system to always power-up to a
preset value stored in nonvolatile memory; then during
system operation minor adjustments could be made. The
adjustments might be based on user preference, system
parameter changes due to temperature drift, etc...
The state of U/D may be changed while CS remains LOW.
This allows the host system to enable the device and then
move the wiper up and down until the proper trim is attained.

Power-up and Down Requirements
There are no restrictions on the power-up or power-down
conditions of VCC and the voltages applied to the
potentiometer pins provided that VCC is always more
positive than or equal to VH, VL, and VW, i.e., VCC ≥ VH, VL,
VW. The VCC ramp rate spec is always in effect.

Applications Information
Electronic digitally controlled (XDCP) potentiometers provide
three powerful application advantages; (1) the variability and
reliability of a solid-state potentiometer, (2) the flexibility of
computer-based digital controls, and (3) the retentivity of
nonvolatile memory used for the storage of multiple
potentiometer settings or data.
