Specialized Procurement Notes

Verify the specific suffix E1MAE40 against official NXP documentation to confirm package type, temperature range, and lead-free status. Ensure compatibility with the target FlexRay physical layer transceiver. Confirm that the ordering part number matches the exact revision required for your design-in process. Check for any specific marking or traceability requirements mandated by your automotive quality standards.

Specialized Selection Notes

Select this component when a dedicated FlexRay controller is required for safety-critical automotive applications. Compare pin counts and interface options with alternative controllers like the MFR4200 if system integration constraints differ. Evaluate the need for integrated PHY versus external transceivers based on board space and power budget. Consider the long-term availability program offered by NXP for automotive components.

Specialized Part Context

This part belongs to the NXP FlexRay family of communication controllers, designed specifically for automotive Ethernet and FlexRay networks. It complements other NXP automotive processors such as the MPC55xx series MCUs, which often serve as the host processors in FlexRay nodes. The controller works in conjunction with adaptor boards like the FLXRAYADPT500 for evaluation and development purposes.

Specialized Replacement Considerations

Public confirmed substitute part numbers include the MFR4200. Verify functional equivalence regarding pinout and software compatibility before substitution. Consult NXP documentation for detailed cross-reference information.
