Advance Information
Document Number: MC33389
Rev. 5.0, 3/2007
System Basis Chip with Low
Speed Fault Tolerant CAN
The 33389 is a monolithic integrated circuit combining many
functions frequently used by automotive Engine Control Units (ECUs).
It incorporates a low speed fault tolerant CAN transceiver.
Features
• Dual Low Drop Voltage Regulators, with Respectively 100 mA and
200 mA Current Capabilities, Current Limitation, and Over
Temperature Detection with Pre-warning
• 5.0 V Output Voltage for V1 Regulator
• Three Operational Modes (Normal, Stand-by, and Sleep Modes)
Separated from the CAN Interface Operating Modes
• Low Speed 125 kBaud Fault Tolerant CAN Interface, Compatible
with 33388 Stand Alone Physical Interface
• V1 Regulator Monitoring and Reset Function
• Three External High Voltage Wake-Up Inputs, Associated with V3
