The NXP® MCZ33903CD5EK is part of a second generation family of system basis chips, combining multiple features and enhanced module design.
- The MCZ33903CD5EK 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.
Feature
- 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
