X9271  
®
Single Supply/Low Power/256-Tap/SPI Bus  
Data Sheet  
March 31, 2005  
FN8174.1  
DESCRIPTION  
The X9271 integrates a single digitally controlled  
Single Digitally-Controlled (XDCP™)  
Potentiometer  
potentiometer (XDCP) on  
integrated circuit.  
a
monolithic CMOS  
FEATURES  
• 256 Resistor Taps  
• SPI Serial Interface for write, read, and transfer  
operations of the potentiometer  
• Wiper Resistance, 100Ω typical @ V  
• 16 Nonvolatile Data Registers  
• Nonvolatile Storage of Multiple Wiper Positions  
• Power-on Recall. Loads Saved Wiper Position on  
Power-up.  
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 SPI bus  
interface. The potentiometer has associated with it a  
volatile Wiper Counter Register (WCR) and a four  
nonvolatile 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. Powerup recalls the contents of the default  
data register (DR0) to the WCR.  
= 5V  
CC  
• Standby Current < 3µA Max  
• V : 2.7V to 5.5V Operation  
CC  
• 50kΩ, 100kΩ versions of End to End Resistance  
• 100 yr. Data Retention  
• Endurance: 100,000 Data Changes per Bit per  
Register  
The XDCP can be used as  
a three-terminal  
• 14-Lead TSSOP  
• Low Power CMOS  
potentiometer or as a two terminal variable resistor in  
a wide variety of applications including control,  
parameter adjustments, and signal processing.
