INSTRUCTIONS AND PROGRAMMING
The INC, U/D and CS inputs control the movement of
the wiper along the resistor array. With CS set LOW the
device is selected and enabled to respond to the U/D
and INC inputs. HIGH to LOW transitions on INC will
increment or decrement (depending on the state of the
U/D input) a five bit counter. The output of this counter
is decoded to select one of thirty two wiper positions
along the resistive array.
The value of the counter is stored in nonvolatile mem-
ory whenever CS transitions HIGH while the INC input
is also HIGH. In order to avoid an accidental store dur-
ing power-up, CS must go HIGH with V
CC
during initial
power-up. When performing multiple write operations,
V
CC
must not decrease by more than 150mV from its
initial value. When left open, the CS pin is internally
pulled up to V
CC
by an internal 30K resistor.
The system may select the X93154, move the wiper
and deselect the device without having to store the lat-
est wiper position in nonvolatile memory. After the
wiper movement is performed as described above and
once the new position is reached, the system must
keep INC LOW while taking CS HIGH. The new wiper
position will be maintained until changed by the system
or until a power-up/down cycle recalled the previously
stored data. In order to recall the stored position of the
wiper on power-up, the CS pin must be held HIGH.
This procedure allows the system to always power-up
to a preset value stored in nonvolatile memory; then
during system operation minor adjustments could be
made. The adjustments might be based on user prefer-
ence, system parameter changes due to temperature
drift, or other system trim requirements.
The state of U/D may be changed while CS remains
LOW. This allows the host system to enable the device
and then move the wiper up and down until the proper
trim is attained.
