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 (50KΩ) each tap point repre-

sents 505Ω.

All Xicor nonvolatile memories are designed and tested

for applications requiring extended endurance and data

retention.

X9C102/103/104/503 PIN DESCRIPTIONS PIN CONFIGURATION VH and VL The high (VH) and low (VL) terminals of the X9C102/103/ 104/503 are equivalent to the fixed terminals of a mechanical potentiometer. The minimum voltage is –5V and the maximum is +5V. It should be noted that the terminology of VL and VH references the relative position of the terminal in relation to wiper movement direction selected by the U/D input and not the voltage potential on the terminal.

X9C102/103/104/503 DEVICE OPERATION OPERATION NOTES There are three sections of the X9C102/103/104/503: the input control, counter and decode section; the nonvolatile memory; and the resistor array. The input control section operates just like an up/down counter. The output of this counter is decoded to turn on a single electronic switch connecting a point on the resistor array to the wiper output.
