Advance Information  
System Basis Chip Gen2 with High  
Speed CAN and LIN Interface  
33904  
33905  
The 33904/5 is the second generation family of System Basis Chips  
which combine several features and enhance present module designs.  
The device works as an advanced power management unit for the  
MCU and additional integrated circuits such as sensors, CAN  
transceivers. It has a built-in enhanced high speed CAN interface  
(ISO11898-2 and -5), with local and bus failure diagnostics, protection,  
and fail safe operation mode. The SBC may include one or two LIN 2.1  
interfaces with LIN output pin switches. It includes up to 4 wake-up  
input pins than can also be configured as output drivers for flexibility.  
SBC CAN GEN2  
This device implements multiple Low Power modes, with very low-  
current consumption. In addition, the device is part of a family concept  
where pin compatibility, among the various devices with and without  
LIN interfaces, add versatility to module design.

Package  
• Protected 5.0V or 3.3V regulators for MCU (part number selectable)  
and additional ICs (SPI configurable) with optional external PNP  
usage to increase current capability for MCU.  
• Fully-protected embedded 5.0 V regulator for the CAN driver  
• Extremely low quiescent current in low power modes  
• Multiple under-voltage detections to address various MCU  
specifications and system operation modes (i.e. cranking)  
• Multiple wake-up sources in low power modes: CAN or LIN bus, I/O  
transition, automatic timer, SPI message, and VDD over-current  
detection.
