X93156
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 memory
whenever CS transitions HIGH while the INC input is also
HIGH. In order to avoid an accidental store during power-
up, CS must go HIGH with V
CC
during initial power-up.
When left open, the CS pin is internally pulled up to V
CC
by an internal 30k resistor.
The system may select the X93156, move the wiper and
deselect the device without having to store the latest
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 preference, 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.
