X9221A

64 Taps, 2-Wire Serial Bus

Data Sheet

September 14, 2005

FN8163.1

DESCRIPTION

Dual Digitally Controlled Potentiometer

(XDCP™)

The X9221A integrates two digitally controlled potenti-

ometers (XDCP) on a monolithic CMOS integrated

microcircuit.

FEATURES

• 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 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

—2kΩ, 10kΩ, 50kΩ

• Resolution: 64 taps each pot

• 20 Ld plastic DIP and 20-lead 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.
