System Basis Chip with CAN High-Speed and LIN Interface
- This page contains information on a product that is not recommended for new designs.
The NXP® MC34903 is an analog companion chip for the MCU and combines several voltage regulators, interface, monitoring and control, and other features to enhance present module designs targeting the industrial market.
- 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 or one LIN 2.1 interface with LIN output pin switches
- It includes up to three wake-up input pins that can also be configured as output drivers for flexibility
- This device is powered by SMARTMOS® technology
32SOICWEP_PROD
Product Details
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
- Very low quiescent current in LP modes
- Fully protected embedded 5.0 V regulator for the CAN driver
- Multiple undervoltage detections to address various MCU specifications and system operation modes
- Auxiliary 5.0 or 3.3 V SPI configurable regulator, for additional ICs, with overcurrent detection and undervoltage 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 overcurrent 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 1 LIN, compatible to J2602-2 and LIN 2.1
