- Comprehensive connectivity suite supporting CANbus and USB
Applications
- Automotive body electronics
- Instrument clusters
- Infotainment systems
- Gateway controllers
Procurement Notes
Verify the specific suffix 'EFP' corresponds to the 100-TQFP package and tape-and-reel packaging format. Confirm that the 'AUT' designation aligns with your project's requirement for AEC-Q100 qualified components. Ensure compatibility with the specified operating temperature range and voltage supply requirements before finalizing procurement.
Selection Notes
Select this component when automotive certification is mandatory alongside high-performance computing needs. It offers a balance of processing power and peripheral richness suitable for complex embedded tasks. Consider pin count and memory size relative to application demands compared to other SAM E5x variants.
Part Context
This part belongs to the Microchip SAM E51 series, which extends the capabilities of the SAM D51 family with added automotive qualifications. It shares architectural similarities with other Cortex-M4F devices but distinguishes itself through its robust feature set tailored for demanding automotive environments.
Replacement Considerations
ATSAMD51N19A-AUT-EFP serves as a non-automotive alternative with identical specifications but without AEC-Q100 certification. ATSAME51J19A-AUT-EFP provides the same core functionality in a smaller 64-TQFP package.
