Terminal Voltages ±5V, 32 Taps, Log Taper Single Digitally Controlled
Potentiometer (XDCP™)
The Intersil X9314 is a solid state nonvolatile potentiometer and
is ideal for digitally controlled resistance trimming.
Features
• Solid State Potentiometer
The X9314 is a resistor array composed of 31 resistive
elements. Between each element and at either end are tap
points accessible to the wiper element. 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 Taps
• 10kEnd to End Resistance
• Three-Wire Up/Down Serial Interface
• Wiper Resistance, 40Typical
• Nonvolatile Storage and Recall on Power-up of Wiper
Position Standby Current < 500µA Max (Total Package)
The XDCP 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, and
signal processing.
• V

Principles of Operation
There are three sections of the X9314: 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
potential at that point to the wiper.
deselect the device without having to store the latest wiper
position in nonvolatile memory. The wiper movement is
performed as described above; once the new position is
reached, the system would keep the INC LOW while taking CS
HIGH. The new wiper position would be maintained until
changed by the system or until a power-up/down cycle recalled
the previously stored data.
This would allow 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 INC, U/D and CS inputs control the movement of the wiper
along the resistor array. With CS set LOW the X9314 is
selected and enabled to respond to the
The state of U/D may be changed while CS remains LOW. This
allows the host system to enable the X9314 and then move the
wiper up and down until the proper trim is attained.
U/D and INC inputs. HIGH to LOW transitions on INC will
increment or decrement (depending on the state of the U/D
input) a five bit counter. The output of this counter is decoded
to select one of thirty-two wiper positions along the resistive
array.
