MCZ33903D3EKR2

Specialized Overview

The MCZ33903D3EKR2 is a System Basis Chip (SBC) from the NXP MC33903 family, designed for advanced power management in automotive and industrial applications. It integrates an enhanced high-speed CAN interface compliant with ISO11898-2 and -5, supporting baud rates from 40 kb/s to 1.0 Mb/s. The device features a 3.3 V main voltage regulator for MCU supply, powered by SMARTMOS technology. It includes one LIN 2.1 interface with master termination capability and supports up to four wake-up input pins. The component operates within a supply voltage range of 5.5 V to 28 V and functions across a temperature range of -40 °C to +125 °C.

Specialized Feature Summary

• Integrates an enhanced high-speed CAN physical interface with local and bus failure diagnostics.
• Includes a single LIN 2.1 interface compatible with J2602-2 standards.
• Features multiple low-power modes with extremely low quiescent current consumption.
• Provides comprehensive protection including voltage, current, and temperature monitoring.

Specialized Applications

• Aircraft and marine systems
• Automotive and robotic systems
• Industrial actuator controls

Specialized Procurement Notes

Verify the specific ordering suffix EK/R2 confirms lead-free packaging and reel format. Confirm the 'D' version designation indicates the recommended design revision for new implementations. Ensure compatibility with the required 32-pin SOIC exposed pad package footprint during procurement planning.

Specialized Selection Notes

Select this part when a 3.3 V MCU supply is required alongside integrated CAN and LIN communication capabilities. The D3 variant specifically provides zero auxiliary regulators but includes one LIN interface. Verify that the single wake-up configuration meets system requirements before choosing over variants with additional I/O or LIN ports.

Specialized Part Context

This component belongs to the MC33903/4/5 second-generation SBC family. It shares pin compatibility with other devices in the series, such as the MCZ33903DS5EK/R2, facilitating versatile module designs. The 'D' version represents the latest recommended design iteration, resolving previous errata associated with earlier B and C versions.

Specialized Replacement Considerations

Direct replacement options within the same family include MCZ33903DS5EK/R2 for single LIN 5.0 V configurations. For dual LIN interfaces, consider MCZ33903DD3EK/R2. Ensure the alternative part number matches the required output voltage and LIN interface count.
