Digitally Controlled Potentiometer
(XDCP™)
The Intersil X93154 is a digitally controlled potentiometer
(XDCP). The device consists of a resistor array, wiper
switches, a control section, and nonvolatile memory. The
wiper position is controlled by a 3-wire interface.
The potentiometer is implemented by a resistor array
composed of 31 resistive elements and a wiper switching
network. 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
during a subsequent power-up operation.
The device is connected as a two-terminal variable resistor
and can be used in a wide variety of applications including:
- Bias and Gain Control
- LCD Contrast Adjustment

NOTES:
1. Add "T1" suffix for tape and reel. Please refer to TB347 for details on reel specifications.
2. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100% matte
tin plate plus anneal (e3 termination finish, which is 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.
3. For Moisture Sensitivity Level (MSL), please see product information page for X93154. For more information on MSL, please see tech brief
TB363.

BRIEF DESCRIPTION
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.
Up/Down (U/D). The U/D input controls the direction of the wiper movement and whether the counter is incremented
or decremented.
RH. The RH and RL pins of the X93154 are equivalent to the fixed terminals of a mechanical potentiometer. The
minimum voltage is VSS and the maximum is VCC. The terminology of RH and RL references the relative position of
the terminal in relation to wiper movement direction selected by the U/D input.
Ground.
No Connection (or can be connected to any voltage between VSS and VCC).
RL. The RH and RL pins of the X93154 are equivalent to the fixed terminals of a mechanical potentiometer. The
minimum voltage is VSS and the maximum is VCC. The terminology of RH and RL references the relative position of
the terminal in relation to wiper movement direction selected by 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 X93154 will be placed in the low power standby mode until the device is selected once again.
