FN8178.2
Single Digitally Controlled Potentiometer
(XDCP™)
The Intersil X9314 is a solid state nonvolatile potentiometer and
is ideal for digitally controlled resistance trimming.
The X9314 is a resistor array composed of 31 resistive
elements. Between each element and at either end are tap
points accessible to the wiper element. The position of the
wiper element is controlled by the CS, U/D, and INC inputs.
The position of the wiper can be stored in nonvolatile
memory and then be recalled upon a subsequent power-up
operation.
The XDCP can be used as a three-terminal potentiometer or
as a two-terminal variable resistor in a wide variety of
applications including control, parameter adjustments, and
signal processing.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate
termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
Pin Descriptions
VH/RH and VL/RL
The high (VH/RH) and low (VL/RL) terminals of the X9314
are equivalent to the fixed terminals of a mechanical
potentiometer. The minimum voltage is –5V and the
maximum is +5V. It should be noted that the terminology of
VL/RL and VH/RH references the relative position of the
terminal in relation to wiper movement direction selected by
the U/D input and not the voltage potential on the terminal.
VW/RW
VW/RW is the wiper terminal, equivalent to the movable
terminal of a mechanical potentiometer. The position of the
wiper within the array is determined by the control inputs.
The wiper terminal series resistance is typically 40.
Up/Down (U/D)
The U/D input controls the direction of the wiper movement
and whether the counter is incremented or decremented.
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 X9314 will be placed in
the low power standby mode until the device is selected
once again.
