The NXP® MC33784 is a follower distributed system interface bus (DBUS), version 2.02 compatible device optimized as a sensor interface.

  • Contains circuits to power sensors such as accelerometers and to digitize the analog level from the sensor
  • The device is controlled by commands over the bus, and returns measured data and other information over the bus
  • Tools: Limited Evaluation boards available; contact sales
