Overview

www.DataSheet.co.kr Freescale Semiconductor Advance Information Document Number: MC33784 Rev 3.0, 11/2009 DSI 2.02 Sensor Interface The 33784 is a slave, Distributed System Interface Bus (DBUS), version 2.02 compatible device, optimized as a sensor interface.

The device 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.

Key Features

  • DSI version 2.02 compatible 2-channel, 10-bit analog-to-digital converter (ADC) 3 pins configurable as logic inputs or outputs Provides regulated +5.0v output for sensor power from bus On-board clock (no external elements required) Includes bus switches on bus and bus return Pb-free packaging designated by suffix code EF 33784 SENSOR.
