NXP Semiconductors MC33903, MC33904, & MC33905 System Basis Chips

NXP Semiconductors MC33903, MC33904, and MC33905 System Basis Chips are second generation SBCs, combining several features and enhancing module design. The MC33903, MC33904, and MC33905 devices work as advanced power management units for an MCU with additional integrated circuits such as sensors and CAN transceivers. These devices have a built-in enhanced high-speed CAN interface (ISO11898-2 and -5) with local and bus failure diagnostics, protection, and fail-safe operation modes. These SBCs may include zero, one, or two LIN 2.1 interfaces with LIN output pin switches. They include up to four wake-up input pins that can also be configured as output drivers for flexibility. The MC33903, MC33904, and MC339053 SBCs implement multiple low-power (LP) modes, with very low-current consumption.

The NXP Semiconductors MC33903, MC33903, & MC33903 System Basis Chips are offered in SOIC32 and SOIC54 packages for design flexibility.

Features

  • Voltage regulator for MCU, 5.0V or 3.3V, 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 undervoltage detections to address various MCU specifications and system operation modes (i.e. cranking)
  • Auxiliary 5.0V or 3.3V 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 40kb/s to 1.0Mb/s
  • Scalable product family of devices ranging from 0 to 2 LINs which are compatible to J2602-2 and LIN 2.1
