Technical Data
SBC Gen2 with CAN High Speed
and LIN Interface
The 33903/4/5 is the second generation family of the System Basis
Chip (SBC). It combines several features and enhances present
module designs. The device works as an advanced power
management unit for the MCU with additional integrated circuits such
as sensors and 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 modes. The SBC may
include zero, one or two LIN 2.1 interfaces with LIN output pin switches.
It includes up to four wake-up input pins that can also be configured as
output drivers for flexibility.
This device implements multiple Low-power (LP) modes, with very
low-current consumption. In addition, the device is part of a family
concept where pin compatibility adds versatility to module design.
The 33903/4/5 also implements an innovative and advanced fail-safe
state machine and concept solution.
Features
• Voltage regulator for MCU, 5.0 or 3.3 V, part number selectable, with
possibility of usage external PNP to extend current capability and
share power dissipation
• Voltage, current, and temperature protection
• Extremely low quiescent current in LP modes
• Fully-protected embedded 5.0 V regulator for the CAN driver
• Multiple under-voltage detections to address various MCU
specifications and system operation modes (i.e. cranking)
• Auxiliary 5.0 or 3.3 V SPI configurable regulator, for additional ICs,
with over-current detection and under-voltage protection
• MUX output pin for device internal analog signal monitoring and
power supply monitoring
• Advanced SPI, MCU, ECU power supply, and critical pins
diagnostics and monitoring.
• Multiple wake-up sources in LP modes: CAN or LIN bus,
I/O transition, automatic timer, SPI message, and VDD over-current
detection.
• ISO11898-5 high-speed CAN interface compatibility for baud rates of
40 kb/s to 1.0 Mb/s
• Scalable product family of devices ranging from 0 to 2 LINs which are
compatible to J2602-2 and LIN 2.1
