DESCRIPTION
The Xicor X9313 is a solid state nonvolatile potentiom-
eter and is ideal for digitally controlled resistance
trimming.
The X9313 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.
The resolution of the X9313 is equal to the maximum
resistance value divided by 31. As an example, for the
X9313W (10K) each tap point represents 323.
All Xicor nonvolatile memories are designed and tested
for applications requiring extended endurance and data
retention.

PIN DESCRIPTIONS
VH and VL
The high (VH) and low (VL) terminals of the X9313 are
equivalent to the fixed terminals of a mechanical potenti-
ometer. 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.
VW
Vw is the wiper terminal, equivalent to the movable
terminal of a mechanical potentiometer. The position
of the wiper within the array is determined by the
control inputs. The wiper terminal series resistance is
typically 40.
Up/Down (U/D)
The U/D input controls the direction of the wiper move-
ment and whether the counter is incremented or
decremented.
Increment (INC)
The INC input is negative-edge triggered. Toggling INC
will move the wiper and either increment or decrement
the counter in the direction indicated by the logic level on
the U/D input.
Chip Select (CS)
The device is selected when the CS input is LOW. The
current counter value is stored in nonvolatile memory
when CS is returned HIGH while the INC input is also
HIGH. After the store operation is complete the X9313
will be placed in the low power standby mode until the
device is selected once again.
