Low Noise, Low Power, Volatile Single Digitally Controlled (XDCP™)
Potentiometer
The Intersil X9015 is a 32 tap potentiometer that is volatile.
Features
The device consists of a string of 31 resistors that can be
• 32 taps
programmed to connect the R /V wiper output with any of
W
W
the nodes between the connecting resistors. The connection
point of the wiper is determined by information
communicated to the device on the 3-wire port. The 3-wire
port changes the tap position by a falling edge on the
increment pin. The direction the wiper moves is determined by
the state of the up/down pin. The wiper position at power up is
Tap #15.
• Three-wire up/down serial interface
• V = 2.7V–5V
CC
• Operating I
= 50µA max.
CC
• Standby current = 1µA max.
• R = 10k, 50k
TOTAL
• Packages 8 Ld SOIC, 8 Ld MSOP
The X9015 can be used in a wide variety of applications that
require a digitally controlled variable resistor to set analog
values.
• Pb-free plus anneal available (RoHS compliant)

of the terminal in relation to wiper movement direction selected
by the U/D input, and not the voltage potential on the terminal.
When the device is powered-down, the wiper position is lost.
When power is restored, the wiper is set to Tap #15.
RW/VW
R /V is the wiper terminal and is equivalent to the movable

terminal of a mechanical potentiometer. The position of the
wiper within the array is determined by the control inputs. The
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 five bit counter. The output of this
counter is decoded to select one of thirty two wiper positions
along the resistive array.
wiper terminal series resistance is typically 200 at V =5V.
CC
At power up the wiper position is at Tap #15. (V /R =Tap #0).
L
L
Up/Down (U/D)
The U/D input controls the direction of the wiper movement and
whether the tap position is incremented or decremented.
Increment (INC)
The system may select the X9015, move the wiper and deselect
the device. The new wiper position will be maintained until
changed by the system or until a power-up/down cycle.
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.
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.
Chip Select (CS)
The device is selected when the CS input is LOW. When CS is
returned HIGH while the INC input is also HIGH the X9015 will
be placed in the low power standby mode until the device is
selected once again.

Principles Of Operation
There are two sections of the X9015: the input control, counter
and decode section; 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. The
resistor array is comprised of 31 individual resistors connected
in series.
The wiper, when at either fixed terminal, acts like its mechanical
equivalent and does not move beyond the last position. That is,
