Preliminary Information  
Single Digitally-Controlled (XDCP) Potentiometer  
FEATURES  
DESCRIPTION  
• 1024 Resistor Taps – 10-Bit Resolution  
• SPI Serial Interface for write, read, and transfer  
operations of the potentiometer  
The X9111 integrates a single digitally controlled  
potentiometer (XDCP) on  
integrated circuit.  
a
monolithic CMOS  
• Wiper Resistance, 40Typical @ 5V  
• Four Non-Volatile Data Registers  
• Non-Volatile Storage of Multiple Wiper Positions  
• Power On Recall. Loads SavedWiper Position on  
Power Up.  
The digital controlled potentiometer is implemented  
using 1023 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  
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. Powerup recalls the  
contents of the default data register (DR0) to the WCR.  
• Standby Current < 3µA Max  
• V : 2.7V to 5.5V Operation

• 100KEnd to End Resistance  
• 100 yr. Data Retention  
• Endurance: 100, 000 Data Changes Per Bit Per  
Register  
• 14-Lead TSSOP, 15-Lead CSP (Chip Scale  
Packaging)  
• Low Power CMOS  
• Single Supply version of the X9110  
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.
