Technical Data
Distributed System Interface
(DSI) 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 sensor. The device is controlled by commands over the
DSI bus and returns measured data over the bus.
Features
• Conforms to DSI Specification Version 1
• 4-Channel, 8-Bit Analog-to-Digital Converter (ADC)
• 4 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
• Undervoltage Fault Detection and Signaling
• 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
• Detects Short to Battery on Bus Switch and Prevents Its Closure
• Pb-Free Packaging Designated by Suffix Code EF

Notes
1. ESD1 performed in accordance with the Human Body Model (CZAP = 100 pF, RZAP = 1500 Ω), ESD2 performed in accordance with the
Machine Model (CZAP = 200 pF, RZAP = 0 Ω).
2. Pin soldering temperature limit is for 10 seconds maximum duration. Not designed for immersion soldering. Exceeding these limits may
cause malfunction or permanent damage to the device.
3. Freescale’s Package Reflow capability meets Pb-free requirements for JEDEC standard J-STD-020C. For Peak Package Reflow
Temperature and Moisture Sensitivity Levels (MSL),
Go to www.freescale.com, search by part number [e.g. remove prefixes/suffixes and enter the core ID to view all orderable parts. (i.e.
MC33xxxD enter 33xxx), and review parametrics.
