Low Noise, Low Power, 3 wire Up/Down,
32 Taps
The Intersil X93156 is a three-terminal 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 an Up/Down
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 a nonvolatile memory and then be recalled upon
a subsequent power-up operation.
The device can be used as a three-terminal potentiometer or
as a two terminal variable resistor in a wide variety of
applications including the programming of bias voltages,
LCD brightness and contrast control as well as the
implementation of ladder networks.

BRIEF DESCRIPTION
INC 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.
U/D Up/Down (U/D). The U/D input controls the direction of the wiper movement and whether the counter is incremented or
decremented.
RH RH. The RH and RL pins of the X93156 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.
VSS Ground.
Rw RW. The Rw pin of the X93156 is the wiper terminal of the potentiometer which is equivalent to the movable terminal of a
mechanical potentiometer.
RL RL. The RH and RL pins of the X93156 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.
CS 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 X93156 will
be placed in the low power standby mode until the device is selected once again.
VCC Supply Voltage.
