Advance Information
Two-Channel Distributed
System Interface (DSI) Physical
Interface Device
The 33790 is a dual channel physical layer interface IC for the
Distributed System Interface (DSI) bus. It is designed to meet
automotive requirements. It can also be used in non automotive
applications. It supports bidirectional communication between slave
and master ICs. Some slave devices derive a regulated 5.0 V from
the bus, which can be used to power sensors, thereby eliminating the
need for additional circuitry and wiring.
Features
• Two Independent DSI Compatible Buses
• Pinout Matched to MC68HC55 (SPI to DSI Logic)
• Wave-Shaped Bus Output Voltage
• Independent Thermal Shutdown and Current Limit
• Return Signalling Current Detection
• Internal Logic Input Pull ups and Pull downs
• On-Board Charge Pump
• 2.0 kV ESD Capability
• Communications Rate Up to 150 kbps
• Pb-Free Packaging Designated by Suffix Code EG

REVISION HISTORY
REVISION HISTORY
DESCRIPTION OF CHANGES
• Implemented Revision History page
• Converted to Freescale format
• Updated data sheet format
• Removed Peak Package Reflow Temperature During Reflow (solder reflow) parameter from
Maximum Ratings on page 4. Added note with instructions to obtain this information from
www.freescale.com.
• Minor correction changes to Figure 1 and ordering information
• Restated note 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. on
