Up/Down Interface

The Intersil ISL95310 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 an 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 wiper of each

potentiometer has an associated volatile Wiper Counter

that can be directly written to and read by the user. The

contents of the WR controls the position of the wiper on the

resistor array through the switches. At power-up, the device

recalls the contents of the default data registers to the

corresponding WR. 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.

The device can be used as a three-terminal potentiometer or

as a two-terminal variable resistor in a wide variety of

applications including:

• LCD contrast control

• Parameter and bias adjustments

• Mechanical potentiometer replacement

• Industrial and automotive control

Add “-TK” suffix for tape and reel.

NOTE: 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.
