Low Noise/Low Power/SPI Bus  
Sheet  
January 14, 2009  
FN8196.4  
Single Digitally Controlled (XDCP™)  
Potentiometer  
Features  
• Single Voltage Potentiometer  
• 64 Resistor Taps  
Description  
• SPI Serial Interface for Write, Read, and Transfer  
Operations of the Potentiometer  
The X9421 integrates a single digitally controlled  
potentiometer (XDCP) on a monolithic CMOS integrated  
circuit.  
• Wiper Resistance, 150Ω Typical at 5V  
• 4 Non-Volatile Data Registers  
The digital controlled potentiometer is implemented using 63  
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 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.  
• Non-Volatile Storage of Multiple Wiper Positions  
• Power-on Recall. Loads Saved Wiper Position on  
Power-up.  
• Standby Current < 5µA Max  
• V  
CC  
: 2.7V to 5.5V Operation  
• 2.5kΩ, 10kΩ End to End Resistance  
• 100 yr. Data Retention  
• Endurance: 100, 000 Data Changes per Bit per Register  
• 14 Ld TSSOP, 16 Ld SOIC  
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.  
• Low Power CMOS  
• Pb-Free Available (RoHS Compliant)
