FEATURES

DESCRIPTION

• Solid-state ꢂotentiometer

• ꢁ-wire serial interface

• ꢁ3 wiꢂer taꢂ ꢂoints

—Wiꢂer ꢂosition stored in nonvolatile memory

and recalled on ꢂower-uꢂ

The Xicor X9313 is a digitally controlled potentiometer

(XDCP). The device consists of a resistor array, wiper

switches, a control section, and nonvolatile memory.

The wiper position is controlled by a 3-wire interface.

The potentiometer is implemented by a resistor array

composed of 31 resistive elements and a wiper

switching network. Between each element and at

either end are tap points accessible to the wiper

terminal. The position of the wiper element is

controlled by the CS, U/D, and INC inputs. The

position of the wiper can be stored in nonvolatile

memory and then be recalled upon a subsequent

power-up operation.

• ꢁ1 resistive elements

—Temꢂerature comꢂensated

—End to end resistance range ± 320

—Terminal voltagesꢀ –±V to +±V

• Low ꢂower CMOS

—V = ꢁV or ±V

—Active currentꢀ ꢁmA max.

—Standby currentꢀ ±22µA max.

• High reliability

—Enduranceꢀ 122ꢀ222 data changes ꢂer bit

—Register data retentionꢀ 122 years

The device can be used as a three-terminal

potentiometer or as a two-terminal variable resistor in

a wide variety of applications including:

• R
