FEATURES
DESCRIPTION
The Xicor X9C102/103/104/503 is a solid state nonvola-
tile potentiometer and is ideal for digitally controlled
resistance trimming.
The X9C102/103/104/503 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 nonvolatile memory and then be recalled upon a
subsequent power-up operation.
The resolution of the X9C102/103/104/503 is equal to
the maximum resistance value divided by 99. As an
example, for the X9C503 (50K鈩? each tap point repre-
sents 505鈩?
All Xicor nonvolatile memories are designed and tested
for applications requiring extended endurance and data
retention.
