MC33793 : DSI Slave for Remote Sensing
The MC33793 is designed to be used with a sensor or actuator at a
location that is remote from a centralized MCU. This device provides
power, measurement, local logic I/O and communications between the
remote sensor and the centralized MCU over a DSI bus. Sensors such
as accelerometers can be powered from the regulated output of the
device and the resulting analog value from the sensor can be
converted by the MC33793 from an analog level to a digital value for
transmission over the DSI bus in response to a query from the MCU.
Four I/O lines can be configured by the central MCU over the DSI
bus. as analog inputs, digital inputs or digital outputs. This
allows more than one sensor to be remotely controlled and measured
by a single MC33793. Additionally, a high drive logic output is
provided which can be used to power other low-power sensors or
indicators. The MC33793 can replace an MCU and its supporting
hardware in remote measurement and control applications, resulting
in a significant cost reduction.
MC33793 Features
Four channel 8 bit A-to-D converter
Four pins configurable as analog or logic inputs or as logic
outputs
Provides regulated +5.0 V output for sensor power from bus
Additional high-drive logic output
On-board clock (no external elements required)
Field programmable address
Default and field programmable as a DSI daisy chain device
Recognizes reverse initialization for open bus fault tolerance
