PIN DESCRIPTION
SCL: Serial Clock
The CAT5241 serial clock input pin is used to clock
all data transfers into or out of the device.
SDA: Serial Data
The CAT5241 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.
A0, A1, A2, A3: 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 communication with the
CAT5241.
RH, RL: Resistor End Points
The four sets of RH and RL pins are equivalent to the
terminal connections on a mechanical potentiometer.
RW: Wiper
The four RW pins are equivalent to the wiper terminal
of a mechanical potentiometer.
DEVICE OPERATION
The CAT5241 is four resistor arrays integrated with I²C
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 (RH and RL). RH and RL are
symmetrical and may be interchanged. The tap
positions between and at the ends of the series resis–
tors are connected to the output wiper terminals (RW) 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 I²C 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.
