Terminal Voltage 0V to 13.2V, 128 Taps I C  
Interface  
Features  
• Non-volatile solid-state potentiometer  
The Intersil ISL95311 is a digitally controlled potentiometer  
(XDCP). The device consists of a resistor array, wiper  
switches, a control section, and nonvolatile memory. The  
2
• I C serial interface  
• DCP terminal voltage, 0V to +13.2V  
2
wiper position is controlled by an I C interface.  
• 128 wiper tap points - 0.8% resolution  
- 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 wiper of the  
potentiometer has an associated volatile Wiper Counter  
Register (WR) and a non-volatile Initial Value Register (IVR)  
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 IVR to the corresponding WR.  
• 127 resistive elements  
- Temperature compensated  
- Low wiper resistance 70Ω typical @ 3.3V  
• Low power CMOS  
- Standby current, 2µA @ V  
= +3.6V  
CC  
• High reliability  
- Endurance, 200,000 data changes per bit  
The device can be used as a three-terminal potentiometer or  
as a two-terminal variable resistor in a wide variety of  
applications, including:  
- Register data retention 50 years @ T ≤ 75°C  
• R  
TOTAL  
values = 10kΩ, 50kΩ  
• 10-lead MSOP package  
• LCD contrast control  
- Pb-free plus anneal available (RoHS compliant)  
• Parameter and bias adjustments  
• Industrial and automotive control  
• Mechanical pot replacement

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.  
CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
