PIN DESCRIPTIONS
V
The high (V
equivalent to the fixed terminals of a mechanical potenti-
ometer. The minimum voltage is V

CC
. It should be noted that the terminology of V
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.

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
400
.
W
w
is the wiper terminal, equivalent to the movable
Up/Down (U/D)
The U/D input controls the direction of the wiper move-
ment and whether the counter is incremented or decre-
mented.
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 X9315
will be placed in the low power standby mode until the
device is selected once again.
