Pin Descriptions
Host Interface Pins
SERIAL CLOCK (SCL)
The SCL input is used to clock data into and out of the
X9429.
SERIAL DATA (SDA)
SDA is a bidirectional pin used to transfer data into and out of
the device. It is an open drain output and may be wire-ORed
with any number of open drain or open collector outputs. An
open drain output requires the use of a pull-up resistor. For
selecting typical values, refer to the guidelines for calculating
typical values on the bus pull-up resistors graph.
DEVICE ADDRESS (A0, A2, A3)
The Address inputs are used to set the least significant 3 bits
of the 8-bit slave address. A match in the slave address
serial data stream must be made with the Address input in
order to initiate communication with the X9429. A maximum
of 8 devices may occupy the 2-wire serial bus.
Potentiometer Pins
RH/VH, RL/VL
The RH/VH and RL/VL inputs are equivalent to the terminal
connections on either end of a mechanical potentiometer.
RW/VW
The wiper outputs are equivalent to the wiper output of a
mechanical potentiometer.
HARDWARE WRITE PROTECT INPUT WP
The WP pin when low prevents nonvolatile writes to the Data
Registers.
Principals of Operation
The X9429 is a highly integrated microcircuit incorporating a
resistor array and its associated registers and counters and
the serial interface logic providing direct communication
between the host and the XDCP potentiometers.
Serial Interface
The X9429 supports a bidirectional bus oriented protocol.
The protocol defines any device that sends data onto the
