Brief Description
R
W1
. The R
W1
pin of the X93256 is the wiper terminal of the first potentiometer which is equivalent
to the movable terminal of a mechanical potentiometer.
R
L1
. The R
H1
and R
L1
pins of the X93256 are equivalent to the fixed terminals of a
mechanical potentiometer. The minimum voltage is V
SS
and the maximum is V
CC
. The terminol-
ogy of R
H1
and R
L1
references the relative position of the terminal in relation to wiper movement
direction selected by the U/D input.
Chip Select 1 (CS
1
)
. The first potentiometer is selected when the CS
1
input is LOW. The current
counter value is stored in nonvolatile memory when CS
1
is returned HIGH while the INC
1
input is
also HIGH. After the store operation is complete, the first potentiometer of the X93256 will be
placed in the low power standby mode until the first potentiometer is selected once again.
Increment 2 (INC
2
)
. The INC
2
input is negative-edge triggered. Toggling INC
2
will move the wiper
of the second potentiometer and either increment or decrement the counter in the direction indi-
cated by the logic level on the U/D
2
input.
Up/Down 2 (U/D
2
)
. The U/D
2
input controls the direction of the second potentiometer wiper
movement and whether the counter for the second potentiometer is incremented or decremented.
R
H2
. The R
H
2
and R
L2
pins of the X93256 are equivalent to the fixed terminals of a
mechanical potentiometer. The minimum voltage is V
SS
and the maximum is V
CC
. The terminol-
ogy of R
H2
and R
L2
references the relative position of the wiper terminal for the second potenti-
ometer in relation to the wiper movement direction selected by the U/D
2
input.
