Doc. No. 2008, Rev. O
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 R
H
and R
L
equivalent to the high
and low terminals and R
WB
equivalent to the mechanical
potentiometer's wiper. There are 100 available tap
positions including the resistor end points, R
H
and R
L
.
There are 99 resistor elements connected in series
between the R
H
and R
L
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 nonvolatile memory.
PIN DESCRIPTIONS
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 R
H
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
R
L
terminal.
R
H:
High End Potentiometer Terminal
R
H
is the high end terminal of the potentiometer. It is not
required that this terminal be connected to a potential
greater than the R
L
terminal. Voltage applied to the R
H
terminal cannot exceed the supply voltage, V
CC
or go
below ground, GND.
R
WB
: Wiper Potentiometer Terminal (Buffered)
R
WB
is the buffered wiper terminal of the potentiometer. Its
position on the resistor array is controlled by the control
inputs,
INC
, U/
D
and
CS
.
R
L
: Low End Potentiometer Terminal
R
L
is the low end terminal of the potentiometer. It is not
required that this terminal be connected to a potential
less than the R
H
terminal. Voltage applied to the R
L
terminal cannot exceed the supply voltage, V
CC
or go
below ground, GND. R
L
and R
H
are electrically
interchangeable.
CS
: Chip Select
The chip select input is used to activate the control input
