DESCRIPTION
The Xicor X9316 is a solid state “micropower” nonvolatile
potentiometer and is ideal for digitally controlled resis-
tance trimming in battery-powered systems.
The X9316 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
nonvolatile memory and then be recalled upon a subse-
quent power-up operation.
The resolution of the X9316 is equal to the maximum
resistance value divided by 31. As an example, for the
X9316W (10K ) each tap point represents 323 .
All Xicor nonvolatile memories are designed and tested
for applications requiring extended endurance and data
retention.
