Low Noise, Low Power, Low Cost Digitally Controlled Potentiometer (XDCP™)
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
Features
• Solid-state nonvolatile
• 16 wiper taps
• 3-wire up/down serial interface
• V = 2.7V and 5V
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.
CC
• Active current < 50µA max.
• Standby current < 5µA max.
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.
• R
TOTAL
= 10k
• Packages: 8 Ld MSOP, 8 Ld SOIC
• Pb-free plus anneal available (RoHS compliant)
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.

Instructions and Programming
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.

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.
