Digitally Controlled Potentiometer (XDCP™)
Data Sheet
August 17, 2005
FN8240.2
Terminal Voltage ±3V or ±5V, 128 Taps
Up/Down Interface
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.
Features
• Non-Volatile Solid-State Potentiometer
• Up/Down Interface with Chip Select Enable
• DCP Terminal Voltage, ±3V or ±5V
• 128 Wiper Tap Points
- Wiper position stored in nonvolatile memory and
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.

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.
