FN8222.3
Digitally Controlled Potentiometer
(XDCP™)
The X9C102, X9C103, X9C104, X9C503 are Intersils’
digitally controlled (XDCP) potentiometers. The device
consists of a resistor array, wiper switches, a control section,
and non-volatile memory. The wiper position is controlled by
a three-wire interface.
The potentiometer is implemented by a resistor array
composed of 99 resistive elements and a wiper switching
network. Between each element and at either end are tap
points accessible to the wiper terminal. 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 non-volatile
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 ranging from control to signal processing to
parameter adjustment.

NOTES:
1. 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.
2. Pb-free PDIPs can be used for through-hole wave solder processing only. They are not intended for use in Reflow solder processing applications.

DESCRIPTION
INCREMENT
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
The U/D input controls the direction of the wiper movement and whether the counter is incremented or
decremented.

CS
The device is selected when the CS input is LOW. The current counter value is stored in non-volatile memory when
CS is returned HIGH while the INC input is also HIGH. After the store operation is complete the X9C102, X9C103,
X9C104, X9C503 device will be placed in the low power standby mode until the device is selected once again.
