Low Noise, Low Power, 32 Taps 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.
Features
• Solid-state potentiometer
• 3-wire serial 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.
• 32 wiper tap points
- Wiper position stored in nonvolatile memory and
recalled on power-up
• 31 resistive elements
- Temperature compensated
- End to end resistance range ± 20%
- Terminal voltage, 0 to V
CC
• Low power CMOS
The device can be used as a three-terminal potentiometer or
as a two-terminal variable resistor in a wide variety of
applications including:
- V

Principles of Operation
TOP VIEW
There are three sections of the X9315: the input control,
counter and decode section; the nonvolatile memory; and the
resistor array. The input control section operates just like an
up/down counter. The output of this counter is decoded to turn
on a single electronic switch connecting a point on the resistor
array to the wiper output. Under the proper conditions the
contents of the counter can be stored in nonvolatile memory
and retained for future use. The resistor array is comprised of
31 individual resistors connected in series. At either end of the
array and between each resistor is an electronic switch that
transfers the connection at that point to the wiper.

Pin Description
When the device is powered-down, the last wiper position

power is restored, the contents of the memory are recalled and
the wiper is set to the value last stored.

Up/Down (U/D)
The system may select the X9315, move the wiper and
deselect the device without having to store the latest wiper
position in nonvolatile memory. After the wiper movement is
performed as described above and once the new position is
reached, the system must keep INC LOW while taking CS
HIGH. The new wiper position will be maintained until changed
by the system or until a power-up/down cycle recalled the
previously stored data.
The U/D input controls the direction of the wiper movement
and whether the counter is incremented or decremented.
Increment (INC)
The INC input is negative-edge triggered. Toggling INC will
move the wiper and either increment or decrement the counter
in the direction indicated by the logic level on the U/D input.
Chip Select (CS)
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
The device is selected when the CS input is LOW. The current
counter value is stored in nonvolatile memory when CS is
returned HIGH while the INC input is also HIGH. After the store

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.
