Device Operation
serial interface logic, four 6−bit wiper control registers and
sixteen 6−bit, non−volatile memory data registers. Each
resistor array contains 63 separate resistive elements
connected in series. The physical ends of each array are
equivalent to the fixed terminals of a mechanical
potentiometer (R
may be interchanged. The tap positions between and at the
ends of the series resistors are connected to the output wiper

terminals (R
point for each potentiometer is connected to its wiper
terminal at a time and is determined by the value of the wiper
control register. Data can be read or written to the wiper
control registers or the non−volatile memory data registers
via the 2−wire bus. Additional instructions allow data to be
transferred between the wiper control registers and each
respective potentiometer’s non−volatile data registers. Also,
the device can be instructed to operate in an
“increment/decrement” mode.
