The Intersil X9313 is a digitally controlled potentiometer
Features
(XDCP). The device consists of a resistor array, wiper
Solid-state potentiometer
switches, a control section, and nonvolatile memory. The
wiper position is controlled by a 3-wire interface.
3-wire serial interface
The potentiometer is implemented by a resistor array 32 wiper tap points
composed of 31 resistive elements and a wiper switching

NOTE: 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.
*Add T1 suffix for tape and reel. Please refer to TB347 for details on reel specifications.
**AddT2" suffix for tape and reel. Please refer to TB347 for details on reel specifications.
***Pb-free PDIPs can be used for through hole wave solder processing only. They are not intended for use in Reflow solder processing applications.

RW/VW
RW/VW 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
wiper terminal series resistance is typically 40 at V = 5V.
