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 < 5µA max.  
• R  
= 10kΩ  
• Packages: 8 Ld MSOP, 8 Ld 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  
SOIC/MSOP  
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.

Up/Down (U/D)  
The U/D input controls the direction of the wiper movement  
and whether the counter is incremented (up) or decremented  
(down).  
Increment (INC)  
The INC input is negative-edge triggered. Toggling INC will  
move the wiper and either increment or decrement the  
counter in the direction indicated by the logic level on the  
U/D input.  
Chip Select (CS)  
The device is selected when the CS input is LOW. The  
current counter value is stored in nonvolatile memory when  
CS is returned HIGH while the INC input is also HIGH. After  
the store operation is complete the X9116 will be placed in  
the low power standby mode until the device is selected  
once again.

X9116  
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  
adjustments might be based on user preference, system  
parameter changes due to temperature drift, etc.  
Principles of Operation  
There are three sections of the X9116: the input control,  
counter and decode section; the nonvolatile memory; and  
the resistor array. The input control section operates just like  
an up/down counter. The output of this counter is decoded to  
turn on a single electronic switch connecting a point on the  
resistor array to the wiper output. Under the proper  
conditions the contents of the counter can be stored in  
nonvolatile memory and retained for future use. The resistor  
array is comprised of 15 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 pin.  
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.

The wiper, when at either fixed terminal, acts like its

The electronic switches on the device operate in a “make

State Not  
Known  
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 four  
bit counter. The output of this counter is decoded to select  
one of 16 wiper positions along the resistive array.  
N/A

is High  
Impedance  
The value of the counter is stored in nonvolatile memory  
whenever CS transitions HIGH while the INC input is also  
HIGH.  
The system may select the X9116, 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.
