X9421

Power On Recall

DESCRIPTION

The X9421 integrates a single digitally controlled

potentiometer

integrated circuit.

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.

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.
