MCZ33903DP5EK

Specialized Overview

The MCZ33903DP5EK is a System Basis Chip (SBC) from the NXP 33903 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 standards, supporting baud rates from 40 kb/s to 1.0 Mb/s. The device features a configurable main voltage regulator outputting either 5.0 V or 3.3 V, along with multiple wake-up input pins that can be configured as output drivers. It operates within a supply voltage range of 5.5 V to 28 V and supports an operating temperature range from -40 °C to +125 °C. The component utilizes SMARTMOS technology and is housed in a 32-pin SOIC package with an exposed pad.

Specialized Feature Summary

Specialized Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm pin compatibility and feature variations within the 33903 family. Ensure the selected variant matches the required voltage regulator output and LIN interface configuration for the target application design.

Specialized Selection Notes

Select this component when a robust system basis chip with integrated high-speed CAN communication and flexible power management is required. Consider the footprint compatibility with other devices in the 33903/4/5 family if modular design flexibility is needed. Verify that the 32-pin SOIC package meets the thermal and spatial constraints of the PCB layout.

Specialized Part Context

This device belongs to the second-generation 33903/4/5 SBC family, which enhances previous module designs by combining power management with integrated circuits like sensors and transceivers. The 'D' version designation indicates specific internal configurations regarding wake-up inputs and termination resistors compared to 'S' or standard 'P' versions within the same package type.

Specialized Replacement Considerations

Direct replacements within the same family include MCZ33903DS5EK/R2 and MCZ33903DD5EK/R2, provided the LIN interface requirements match. Cross-family alternatives like the MC33905 series offer similar functionality but may require schematic adjustments due to different pin counts or interface configurations.
