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  
Register (WCR) and a four non-volatile Data Registers that  
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  
CC  
• 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)
