PIN DESCRIPTIONS
SCL:
The CAT5419 serial clock input pin is used to clock
all data transfers into or out of the device.
Serial Clock
SDA:
The CAT5419 bidirectional serial data pin is used
to transfer data into and out of the device. The
SDA pin is an open drain output and can be wire-
OR'd with the other open drain or open collector
outputs.
Serial Data
A0, A1, A2, A3:
These inputs set the device address when
addressing multiple devices. A total of sixteen
devices can be addressed on a single bus.
A match in the slave address must be made
with the address input in order to initiate
communication with the CAT5419.
Device Address Inputs
R
H
, R
L
: Resistor End Points
The R
H
and R
L
pins are equivalent to the terminal
connections on a mechanical potentiometer.
R
W
:
The R
W
pins are equivalent to the wiper terminal of
a mechanical potentiometer.
Wiper
WP
:
The
WP
pin when tied low prevents non-volatile
writes to the data registers (change of wiper control
register is allowed) and when tied high or left
floating normal read/write operations are allowed.
See page 7, Write Protection for more details.
Write Protect Input
DEVICE OPERATION
The CAT5419 is two resistor arrays integrated with 2-
wire 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
H
and R
L
). R
H
and R
L
are
symmetrical and may be interchanged. The tap positions
between and at the ends of the series resistors are
connected to the output wiper terminals (R
W
) by a
CMOS transistor switch. Only one tap 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.
