DESCRIPTION

The X9241 integrates four nonvolatile E

controlled potentiometers on a monolithic CMOS micro-

circuit.

The X9241 contains four resistor arrays, each com-

posed of 63 resistive elements. Between each element

and at either end are tap points accessible to the wiper

elements. The position of the wiper element on the array

is controlled by the user through the two-wire serial bus

interface.

Each resistor array has associated with it a wiper counter

written and read by the user. The contents of the wiper

counter register control the position of the wiper on the

resistor array.

The data register may be read or written by the user. The

contents of the data registers can be transferred to the

wiper counter register to position the wiper. The current

wiper position can be transferred to any one of its

associated data registers.

The arrays may be cascaded to form resistive elements

with 127, 190 or 253 taps.
