Procurement Notes

Verify the specific package type and memory configuration against the official Microchip datasheet before ordering. Confirm that the AEC-Q100 qualification status meets your project's reliability standards. Ensure compatibility with existing development tools such as Atmel-ICE or SAM V71-XULT. Check for any recent product change notices regarding pinout or electrical characteristics.

Selection Notes

Select this component when a balance of moderate flash capacity and high-speed processing is required. The 64-pin LQFP package suits designs with limited board space compared to larger variants. Consider the integrated Ethernet peripheral if network connectivity is essential without external chips. Evaluate power consumption profiles against other SAM V71 series options for optimal efficiency.

Part Context

This part belongs to the SAM V71 family of microcontrollers from Microchip Technology. It shares architectural similarities with the SAM E70 and SAM S70 series but offers distinct memory and peripheral configurations. The family targets applications demanding robust performance and connectivity in compact form factors.

Replacement Considerations

ATSAMV71J19B-AAT: Same core and memory but in TFBGA package. ATSAMV71N19B-AABT: Higher memory capacity in BGA package. ATSAMV71Q19B-AABT: Larger package with more I/Os.
