Increment . 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.
R
terminals of a mechanical potentiometer. The minimum voltage is -5V and the maximum is +5V.
The terminology of V
relation to wiper movement direction selected by the U/D input and not the voltage potential on
the terminal.

potentiometer. The position of the wiper within the array is determined by the control inputs. The
wiper terminal series resistance is typically 40Ω.
R
terminals of a mechanical potentiometer. The minimum voltage is -5V and the maximum is +5V.
The terminology of V
relation to wiper movement direction selected by the U/D input and not the voltage potential on
the terminal.
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 op-
eration is complete the X9C102/103/104/503 device will be placed in the low power standby mode
until the device is selected once again.
V
Up/Down. The U/D input controls the direction of the wiper movement and whether the counter
is incremented or decremented.
