X9421  
®
Low Noise/Low Power/SPI Bus  
Data Sheet  
September 23, 2005  
FN8196.1  
DESCRIPTION  
The X9421 integrates a single digitally controlled  
Single Digitally Controlled (XDCP™)  
Potentiometer  
potentiometer (XDCP) on  
integrated circuit.  
a
monolithic CMOS  
FEATURES  
• Single Voltage Potentiometer  
• 64 Resistor Taps  
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. Powerup recalls the contents of  
the default data register (DR0) to the WCR.  
• SPI Serial Interface for Write, Read, and Transfer  
Operations of the Potentiometer  
• Wiper Resistance, 150Ω Typical at 5V  
• 4 Non-Volatile Data Registers  
• 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  
• 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 Plus Anneal Available (RoHS Compliant)
