64 Taps, 2-Wire Serial Bus Dual Digitally Controlled Potentiometer (XDCP™)  
FEATURES  
DESCRIPTION  
• Two XDCPs in one package  
• 2-wire serial interface  
• Register oriented format, 8 registers total  
—Directly write wiper position  
—Read wiper position  
Store as many as four positions per pot  
• Instruction format  
—Quick transfer of register contents to resistor  
array  
The X9221A integrates two digitally controlled potenti-  
ometers (XDCP) on a monolithic CMOS integrated  
microcircuit.  
The digitally 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 2-wire  
bus interface. Each potentiometer has associated with  
it a volatile Wiper Counter Register (WCR) and 2 non-  
volatile Data Registers (DR0:DR1) 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 through the switches. Power up recalls the con-  
tents of DR0 to the WCR.  
• Direct write cell  
—Endurance–100,000 writes per bit per register  
• Resistor array values  
—2k, 10k, 50k  
• Resolution: 64 taps each pot  
• 20 Ld plastic DIP and 20 Ld SOIC packages  
• Pb-free plus anneal available (RoHS compliant)  
The XDCP can be used as a three-terminal potentiom-  
eter or as a two-terminal variable resistor in a wide  
variety of applications including control, parameter  
adjustments, and signal processing.
