Power-up and Power-down Requirements
There are no restrictions on the power-up or power-down
conditions of VCC and the voltages applied to the
potentiometer pins provided that VCC is always more
positive than or equal to VH and VL, i.e., VCC ≥ VH,VL. The
VCC ramp rate specification is always in effect.
Pin Descriptions
In the text, CS, INC, U/D, RH, RW, and RL are used to refer
to either CS1 or CS2, etc. Note: These signals can be
applied independently or at the same time.
RH and RL
The RH and RL pins of the X93256 are equivalent to the
fixed terminals of a mechanical potentiometer. The minimum
voltage is VSS and the maximum is VCC. The terminology of
RH and RL references the relative position of the terminal in
relation to wiper movement direction selected by the U/D
input per potentiometer.
RW
The RW pin of the X93256 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 a single
potentiometer’s 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
pertaining potentiometer’s counter in the direction indicated
by the logic level on the pertaining potentiometer’s U/D
input.
Chip Select (CS)
A potentiometer is selected when the pertaining CS input is
LOW. Its current counter value is stored in nonvolatile memory
when the pertaining CS is returned HIGH while the pertaining
INC input is also HIGH. After the store operation is complete
the affected potentiometer will be placed in the low power
standby mode until the potentiometer is selected once again.
Principles of Operation
There are multiple sections for each potentiometer in the
X93256: an input control, a counter and decode section; the
nonvolatile memory; and a resistor array. Each input control
