DESCRIPTION
The Xicor X9312 is a solid state nonvolatile potentiom-
eter and is ideal for digitally controlled resistance trim-
ming.
The X9312 is a resistor array composed of 99 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.
The resolution of the X9312 is equal to the maximum
resistance value divided by 99. As an example, for the
X9312U (50K
) each tap point represents 505
.
All Xicor nonvolatile memories are designed and tested
for applications requiring extended endurance and data
retention.
