PIN DESCRIPTIONS
SCL:
The CAT5269 serial clock input pin is used to
clock all data transfers into or out of the device.
Serial Clock
SDA:
The CAT5269 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-Ored with the other open drain or open
collector I/Os.
Serial Data

Device Address Inputs
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 communica-
tion with the CAT5269.
R

: Resistor End Points
The two sets of R

pins are equivalent
to the terminal connections on a mechanical
potentiometer.
R

:
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 Write Protection on page 7 for
more details.

DEVICE OPERATION
The CAT5269 is two resistor arrays integrated with a 2-wire serial interface, two 8-bit wiper control registers and eight
8-bit, non-volatile memory data registers. Each resistor array contains 255 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
). 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.
