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: 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
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.

Pin Descriptions
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.
