MC33790 : 2-Channel DSI Physical interface for bus masters
The MC33790 is a dual channel physical layer inter-face IC for
the Distributed Systems Interface (DSI) bus. It connects DSI masters
to DSI slave sensors and actuators. It provides power to the slave
sensors and actuators over the DSI Bus and supports bi-directional
communication between the slave and master ICs over this same bus
wire. When used with other DSI family parts, remote sensing and
control can be easily and inexpensively accomplished. Up to 30
remote devices can be supported by single MC33790. The MC68HC55 is
an SPI to DSI protocol converter which is made to match the pin
connections of the MC33790 and allow any MCU with an SPI to generate
a DSI Bus.
MC33790 Features
Complete power source,transmitter and receiver for two
independent DSI busses
Waveshaped voltage mode transmitter (reduced EMI)
Pinout matched to MC68HC55 for easy PCB layout
Independent 150 mA current limit per channel output
Logic input thresholds are 3.3 V and 5.0 V compatible
