It integrates 1 MB of Flash memory and 384 KB of SRAM within a 100-pin LQFP package. The device supports a wide operating temperature range from -40°C to +105°C and complies with AEC-Q100 standards. Key peripherals include multiple communication interfaces such as CAN, Ethernet, I2C, SPI, UART, USART, and USB, alongside a 12-bit ADC.
Feature Summary
- Automotive qualification compliant with AEC-Q100 standards for reliability in vehicle environments.
- High-performance processing capability driven by the ARM Cortex-M7 core architecture.
- Integrated connectivity suite supporting Ethernet, CAN, and various serial communication protocols.
Applications
- Automotive infotainment systems requiring robust multimedia processing.
- Advanced driver assistance systems (ADAS) utilizing high-speed data handling.
- Industrial control applications demanding extended temperature operation ranges.
Procurement Notes
Verify the specific suffix 'AAB' corresponds to the 100-pin LQFP package variant when sourcing. Confirm that the procurement channel provides documentation attesting to AEC-Q100 compliance status. Ensure compatibility with required operating voltage levels and interface configurations before finalizing orders.
Selection Notes
Select this component for designs necessitating automotive certification combined with high computational throughput. Compare against other SAM V71 variants based on required pin count and memory capacity. Evaluate peripheral availability against system interface requirements to ensure optimal resource utilization.
Part Context
This microcontroller belongs to the Microchip SAM V71 family, designed for high-performance embedded applications. It shares architectural similarities with the SAM E70 and SAM S70 series but distinguishes itself through automotive-specific qualifications and feature sets tailored for demanding operational environments.
Replacement Considerations
ATSAMV71N20B-CBT: Offers identical core specifications but utilizes a TFBGA-100 package instead of LQFP. Verify footprint compatibility and thermal management requirements when considering this alternative.
