Low Power/2-Wire Serial Bus

X9241

Quad Digitally Controlled Potentiometer (XDCP^™)

FEATURES

DESCRIPTION

• Four potentiometers in one package

• 2-wire serial interface

• Register oriented format

The X9241 integrates four digitally controlled

potentiometers (XDCP) on a monolithic CMOS

integrated microcircuit.

—Direct read/write/transfer of wiper positions

—Store as many as four positions per

potentiometer

• Terminal Voltages: ±5V

• Cascade resistor arrays

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 4

nonvolatile Data Registers (DR0:DR3) 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 contents of DR0 to the WCR.

• Low power CMOS

• High Reliability

—Endurance–100,000 data changes per bit per

—Register data retention–100 years

• 16-bytes of nonvolatile memory

• 3 resistor array values

—2KΩ to 50KΩ mask programmable

—Cascadable for values of 500Ω to 200KΩ

• Resolution: 64 taps each pot

• 20-lead plastic DIP, 20-lead TSSOP and 20-lead

SOIC packages

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.
