FN8160.1  
Digitally Controlled Potentiometer  
(XDCP™)  
Features  
• Solid-state nonvolatile  
The Intersil X9116 is a digitally controlled nonvolatile  
potentiometer designed to be used in trimmer applications.  
The pot consists of 15 equal resistor segments that connect  
to the wiper pin through programmable CMOS switches. The  
tap position is programmed through a 3-wire up/down serial  
port. The last position of the wiper is stored in a nonvolatile  
memory location which is recalled at the time of power up of  
the device.  
• 16 wiper taps  
• 3-wire up/down serial interface  
• V  
CC  
= 2.7V and 5V  
• Active current < 50µA max.  
• Standby current < 1µA max.  
• R  
= 10kΩ  
• Packages: MSOP-8, SOIC  
TOTAL  
The wiper moves through sequential tap positions with  
inputs on the serial port. A falling edge on INC (bar) causes  
the tap position to increment one position up or down based  
on whether the U/D (bar) pin is held high or low.  
• Pb-free plus anneal available (RoHS compliant)  
Pinout  
The X9116 can be used in many applications requiring a  
variable resistance. In many cases it can replace a  
mechanical trimmer and offers many advantages such as  
temperature and time stability as well as the reliability of a  
solid state solution.
