DESCRIPTION
The Xicor X9314 is a solid state nonvolatile potentiom-
eter and is ideal for digitally controlled resistance trim-
ming.
The X9314 is a resistor array composed of 31 resistive
elements. Between each element and at either end are
tap points accessible to the wiper element. 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 nonvola-
tile memory and then be recalled upon a subsequent
power-up operation.
All Xicor nonvolatile Digitally Controlled Potentiometers
are designed and tested for applications requiring ex-
tended endurance and data retention.
