• Integrated hardware cryptographic engine for secure data processing
• Dual CAN FD controllers supporting high-speed vehicle communication
• Floating-point unit (FPU) integrated with the Cortex-M7 core

Applications

• Automotive instrument clusters and body control modules
• Advanced driver assistance systems (ADAS)
• Infotainment system controllers
• Industrial motor control applications

Procurement Notes

Verify the specific suffix 'CBT' indicates tape-and-reel packaging upon ordering. Confirm that the AEC-Q100 qualification status meets your project's automotive grade requirements. Ensure the TFBGA-100 footprint matches your PCB layout constraints. Validate supply chain authenticity through authorized Microchip distributors to prevent counterfeit components.

Selection Notes

Select this model when automotive certification is mandatory alongside high-performance computing. Compare against the SAM S70 series if non-automotive industrial use allows for different cost structures. Consider the SAM V70 series if lower memory configurations suffice. Verify interface availability, specifically the requirement for dual CAN FD and USB capabilities.

Part Context

This component belongs to the SAM V71 family of high-performance Flash microcontrollers based on the ARM Cortex-M7 processor. The family is designed for demanding automotive and industrial environments requiring robust security and real-time processing capabilities. The N19 variant specifically denotes the 512 KB Flash and 256 KB SRAM configuration within the 100-pin form factor.
