Overview
The ATSAMV71N20B-AABT is a 32-bit microcontroller from the SAM V71 family, featuring an ARM Cortex-M7 core operating at 300 MHz. It integrates 1 MB of Flash memory and 384 kB of SRAM within a 100-pin LQFP package. The device supports a supply voltage range of 1.7 V to 3.6 V and operates between -40°C and +105°C. Key peripherals include 10 ADC channels with 12-bit resolution, 2 DAC channels, and interfaces such as Ethernet, USB, SPI, I2C, and UART.
Feature Summary
- Automotive-grade reliability certified under AEC-Q100 standards for harsh environments.
- Integrated Audio Video Bridging (AVB) support for deterministic network communication.
- High-performance processing via ARM Cortex-M7 core with integrated FPU.
- Comprehensive connectivity suite including GMAC, USB OTG, and multiple serial interfaces.
Applications
- Automotive infotainment systems requiring high-speed data processing.
- Industrial control networks utilizing EtherCAT or PROFINET protocols.
- Advanced driver-assistance systems (ADAS) sensor fusion units.
- Smart home hubs with audio/video streaming capabilities.
Procurement Notes
Verify the specific suffix 'AABT' against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the 100-LQFP form factor. Cross-reference RoHS compliance status with current manufacturing notices. Confirm availability of development tools like ATSAMV71-XULT for initial prototyping phases.
Selection Notes
Select this component when automotive certification and AVB networking are mandatory requirements. Compare memory sizes against alternatives if larger storage is needed. Evaluate pin count suitability for interface density needs. Consider power consumption profiles relative to system battery constraints during active and sleep modes.
Part Context
Part of the SAM V71 series designed for high-performance embedded applications. Shares architectural similarities with SAM E70 and SAM S70 families but offers distinct peripheral sets optimized for automotive and industrial use cases. Enables scalable design across product lines using common software drivers.
Replacement Considerations
ATSAMV71N20B-ANT: Different package (LQFP vs TFBGA). ATSAMS70N20B-CN: Industrial grade, similar specs but different qualification. Verify pinout compatibility before substitution.
