Volatile Digitally Controlled Potentiometer (XDCP™) Terminal Voltage ±3V or ±5V,
128 Taps Up/Down Interface
The Intersil ISL23710 is a digitally controlled potentiometer
(XDCP). The device consists of a resistor array, wiper
Features
• Up/Down Interface with Chip Select Enable
• DCP Terminal Voltage from ±2.7V to ±5V
• 127 Resistive Elements
- Typical R tempco ±50ppm/°C
switches, and a control section. The wiper position is
controlled by a Up/Down interface.
The potentiometer is implemented by a resistor array
composed of 127 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 wiper register is volatile and is reset to midscale on
power up. The wiper position can be locked while powered
up to prevent inadvertent changes.

Power Up and Down Requirements
The device is selected when the CS input is LOW.
In order to prevent unwanted tap position changes, bring the

power-up. The potentiometer voltages must be applied after
this sequence is completed. During power-up, the data sheet

Principles of Operation
There are three sections of the ISL23710: the input control,
counter and decode section, 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. The resistor array is comprised of 127 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.

The U/D input controls the direction of the wiper movement
and whether the counter is incriminated or decremented.
Instructions and Programming
The INC, U/D and CS inputs control the movement of the wiper
along the resistor array. With CS set LOW the device is
selected and enabled to respond to the 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 seven bit counter.
The output of this counter is decoded to select one of one-
hundred twenty-eight wiper positions along the resistive array.
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.

Bringing CS HIGH after INC is HIGH will cause the wiper value
to be locked until power down (further changes in CS and INC
will not change the wiper position). Otherwise, INC should be
brought HIGH after CS to allow continued wiper changes.
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. During
initial power-up CS must go high along with or before V
avoid an accidental tap position change.
