SBC Gen2 with High-Speed CAN and LIN

MC33905 Active

The NXP MC33905 is part of a second generation family of system basis chips, combining multiple features and enhanced module design.

  • The MC33905 works as an advanced power management unit for the MCU and additional integrated circuits such as sensors and CAN transceivers
  • 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 zero, one or two LIN 2.1 interfaces with LIN output pin switches
  • Includes 2 or 3 wake-up input pins than can also be configured as output drivers for flexibility

Features

Key Features

  • Voltage regulator for MCU, 5.0 V 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
  • Very low quiescent current in low-power 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 V 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 low-power 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
