Document Number: MC33793 Freescale Semiconductor Rev 15.0, 2/2014 Technical Data Distributed System Interface (DSI) 33793/A Sensor Interface The 33793 is a slave Distributed System Interface (DSI) device that is optimized as a sensor interface. The device contains circuits to power sensors such as accelerometers and to digitize the analog level from the DISTRIBUTED SYSTEM INTERFACE sensor. The device is controlled by commands over the DSI bus and returns measured data over the bus. This device is powered using SMARTMOS technology. Features Conforms to DSI specification version 1 4-channel, 8-Bit analog-to-digital converter (ADC) SCALE 2:1 4 pins configurable as analog or logic inputs or as logic outputs EF SUFFIX (Pb-FREE) Provides regulated +5.0 V output for sensor power from bus 98ASB42566B Additional high-drive logic output 16-PIN SOICN Undervoltage fault detection and signaling Applications On-board clock (no external elements required) Simple bus-controlled part for remote control and Field-programmable address sensing Default and field-programmable as a DSI daisy chain device Automotive, aircraft, marine and industrial control Recognizes reverse initialization for open bus fault tolerance and safety systems Detects short to battery on bus switch and prevents its closure Heating and air-conditioning 33790 GND DSIO 33793 X-Y Multiple Accelerometer BUSIN BUSRTN DSI Slaves Error I/O0 Test I/O1 33793 X I/O2 Y I/O3 BUSOUT BusIN H Cap V REGOUT CC GND LOGOUT AGND Figure 1. 33793 Simplified Application Diagram Freescale Semiconductor, Inc., 2006-2014.
