FEATURES  
DESCRIPTION  
• Single Voltage Potentiometer  
The X9421 integrates a single digitally controlled  
• 64 Resistor Taps  
potentiometer (XDCP) on  
integrated circuit.

monolithic CMOS  
• SPI Serial Interface for write, read, and transfer  
operations of the potentiometer  
Wiper Resistance, 150Typical at 5V  
• 4 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 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.

• 14-Lead TSSOP, 16-Lead SOIC  
• Low Power CMOS  
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.
