FN8240.3
Terminal Voltage ±2.7V to ±5V, 128 Taps,
Up/Down Interface
Features
• Non-Volatile Solid-State Potentiometer
• Up/Down Interface with Chip Select Enable
• DCP Terminal Voltage ±2.7V to ±5.5V
• 128 Wiper Tap Points
The Intersil ISL95710 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 Up/Down interface.
- Wiper position stored in nonvolatile memory and
recalled on power-up
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 position of the wiper can be stored in nonvolatile memory
and then be recalled upon a subsequent power-up operation.
• 127 Resistive Elements
- Typical R

1. Add “-T” suffix for tape and reel.
2. Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate
termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are
MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.

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.
During initial power-up CS must go high along with or before
Principles of Operation
There are three sections of the ISL95710: the input control,
wiper counter and decode section; the nonvolatile memory;
and the resistor array. The input control section operates as
an up/down counter. The output of this wiper counter is
decoded to turn on a electronic switch connecting a point on
the resistor array to the wiper output. The contents of the
wiper counter can be stored in nonvolatile memory and
retained for future use. The resistor array is comprised of
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.

stored will be maintained in the nonvolatile memory. When
power is restored, the contents of the memory are recalled
and the wiper is set to the value last stored.
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 wiper counter. The output of this wiper counter is decoded
to select one of 128 wiper positions along the resistive array.
The value of the wiper counter is stored in nonvolatile
memory whenever CS transitions HIGH while the INC input
is also HIGH.
The system may select the ISL95710, 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
recalls 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
