Specialized Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm pinout compatibility and electrical characteristics. Ensure that the selected variant matches the required voltage regulator output and interface configuration for the target application design.

Specialized Selection Notes

Select this component when a single-chip solution combining power management and high-speed CAN communication is required. Consider the 150 mA internal LDO limit; if higher current is needed, evaluate variants supporting external ballast transistors or different family members with increased capacity.

Specialized Part Context

This part belongs to the MC33903/4/5 second-generation SBC family. It shares functional similarities with other devices in the series but differs in specific interface configurations, such as the presence or absence of LIN transceivers and the number of configurable I/O pins available for wake-up functions.

Specialized FAQ

Does the MCZ33903CP5EK include LIN interfaces?

No, the MCZ33903CP5EK does not include LIN interfaces. It features only the high-speed CAN interface. Variants with LIN support typically have 'D' or 'S' in their part number designation.

What is the maximum output current for the MCU voltage regulator?

The MCU voltage regulator (VDD) has a maximum output current of 150 mA. This is lower than other variants in the family that may support up to 300 mA with an external ballast transistor.

Is the device compatible with automotive environmental standards?

Yes, the device is designed for automotive applications, supporting an operating temperature range of -40 °C to +125 °C and meeting relevant EMC/ESD standards.
