MC33903: SBC Gen2 with High-Speed CAN and LIN

Overview

The NXP^® MC33903 is part of a second generation family of system basis chips, combining multiple features and enhanced module design.

The MC33903 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.

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 (except 33903B3/5) 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
This product is included in NXP’s product longevity program , with assured supply for a minimum of 15 years after launch
