X9279

Single Supply/Low Power/256-Tap/2-Wire Bus

Data Sheet

September 23, 2009

FN8175.4

Single Digitally-Controlled (XDCP™)

Potentiometer

Features

• 256 Resistor Taps

The X9279 integrates a single digitally controlled

potentiometer (XDCP) on a monolithic CMOS integrated

circuit.

• 2-Wire Serial Interface for Write, Read, and Transfer

Operations of the Potentiometer

• Wiper Resistance, 100Ω Typical @ 5V

The digital controlled potentiometer is implemented using

255 resistive elements in a series array. Between each

element are tap points connected to the wiper terminal

through switches. The position of the wiper on the array is

controlled by the user through the 2-Wire bus interface. The

potentiometer has associated with it a volatile Wiper Counter

can be directly written to and read by the user. The contents

of the WCR controls the position of the wiper on the resistor

array though the switches. Power-up recalls the contents of

the default data register (DR0) to the WCR.

• 16 Non-volatile Data Registers for Each Potentiometer

• Non-volatile Storage of Multiple Wiper Positions

• Power-on Recall. Loads Saved Wiper Position on

Power-up.

• Standby Current < 5µA Max

• V : 2.7V to 5.5V Operation

• 50kΩ, 100kΩ Versions of End-to-End Resistance

• Endurance: 100,000 Data Changes per Bit per Register

• 100 yr. Data Retention

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.

• 14 Ld TSSOP

• Low Power CMOS

• Pb-Free Available (RoHS Compliant)
