PIN DESCRIPTION
INC
¯¯¯: Increment Control Input
The INC
¯¯¯ input (on the falling edge) moves the wiper in
the up or down direction determined by the condition
of the U/D
¯ input.
U/D
¯: Up/Down Control Input
The U/D
¯ input controls the direction of the wiper
movement. When in a high state and CS
¯¯ is low, any
high-to-low transition on INC
¯¯¯ will cause the wiper to
move one increment toward the RH terminal. When in
a low state and CS
¯¯ is low, any high-to-low transition
on INC
¯¯¯ will cause the wiper to move one increment
towards the RL terminal.
RH: High End Potentiometer Terminal
RH is the high end terminal of the potentiometer. It is
not required that this terminal be connected to a
potential greater than the RL terminal. Voltage applied
to the RH terminal cannot exceed the supply voltage,
VCC or go below ground, GND.
RWB: Wiper Potentiometer Terminal (Buffered)
RWB is the buffered wiper terminal of the poten–
tiometer. Its position on the resistor array is controlled
by the control inputs, INC
¯¯¯, U/D
¯ and CS
¯¯ .
RL: Low End Potentiometer Terminal
RL is the low end terminal of the potentiometer. It is
not required that this terminal be connected to a
potential less than the RH terminal. Voltage applied to
the RL terminal cannot exceed the supply voltage,
VCC or go below ground, GND. RL and RH are electri-
cally interchangeable.
CS
¯¯ : Chip Select
The chip select input is used to activate the control
input of the CAT5111 and is active low. When in a
high state, activity on the INC
¯¯¯ and U/D
¯ inputs will not
affect or change the position of the wiper.
DEVICE OPERATION
The CAT5111 operates like a digitally controlled
potentiometer with RH and RL equivalent to the high
and low terminals and RWB equivalent to the mecha–
nical potentiometer's wiper. There are 100 available
tap positions including the resistor end points, RH and
RL. There are 99 resistor elements connected in
series between the RH and RL terminals. The wiper
terminal is connected to one of the 100 taps and
controlled by three inputs, INC
¯¯¯, U/D
¯ and CS
¯¯ . These
inputs control a seven-bit up/down counter whose
output is decoded to select the wiper position. The
selected wiper position can be stored in nonvolatile
memory using the INC and CS
¯¯ inputs.
With CS
¯¯ set LOW the CAT5111 is selected and will
respond to the U/D
¯ and INC
¯¯¯ inputs. HIGH to LOW
transitions on INC
¯¯¯ wil increment or decrement the
wiper (depending on the state of the U/D
¯ input and
seven-bit counter). The wiper, when at either fixed
terminal, acts like its mechanical equivalent and does
not move beyond the last position. The value of the
counter is stored in nonvolatile memory whenever CS
¯¯
transitions HIGH while the INC
¯¯¯ input is also HIGH.
When the CAT5111 is powered-down, the last stored
wiper counter position is maintained in the nonvolatile
memory. When power is restored, the contents of the
memory are recalled and the counter is set to the
value stored.
With INC
¯¯¯ set low, the CAT5111 may be de-selected
and powered down without storing the current wiper
position in nonvolatile memory. This allows the system
to always power up to a preset value stored in non-
volatile memory.
