Specifications and information herein are subject to change without notice. © Freescale Semiconductor, Inc., 2008 - 2009. All rights reserved. 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. 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 Figure 1. 33784 Simplified Application Diagram (Daisy Chain Shown) SENSOR INTERFACE EF SUFFIX (PB-FREE) 98ASB42566B 16-LEAD SOICN ORDERING INFORMATION Device Temperature Range (TA) Package MCZ33784EF/R2 -40°C to 125°C 16 SOICN 33784 REGOUT RTNIN I/O0 I/O1 I/O2 BUSOUT RTNOUT BUSIN H_CAP 33784 33781 33784 BUS BUSIN AGND BUSOUT RTNIN RTNOUT To other 33784 XY ACCELEROMETER VCC Slaves AGND AN0 AN1 TEST1 TOUT IDDQ TEST2 |
