Power Up and Down Requirements
There are no restrictions on the power-up or power-down
conditions of V
CC
and the voltages applied to the
potentiometer pins provided that V
CC
is always more
positive than or equal to V
H
and V
L
, i.e., V
CC
≥
V
H,
V
L
. The
V
CC
ramp rate spec is always in effect.
Pin Descriptions
R
H
and R
L
The R
H
and R
L
pins of the X93156 are equivalent to the fixed
terminals of a mechanical potentiometer. The minimum
voltage is V
SS
and the maximum is V
CC
. The terminology of
R
H
and R
L
references the relative position of the terminal in
relation to wiper movement direction selected by the U/D
input.
R
w
The Rw pin of the X93156 is the wiper terminal of the
potentiometer which is equivalent to the movable terminal of
a mechanical potentiometer
Up/Down (U/D)
The U/D input controls the direction of the wiper movement
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 X93156 will be placed in
the low power standby mode until the device is selected
once again.
