Overview

The ATSAMV71Q21B-AABT is a high-performance 32-bit Arm Cortex-M7 microcontroller designed for automotive and high-end industrial applications. Operating at up to 300MHz, it features 2MB of Flash and 384KB of RAM, providing the computational power and memory density required for complex real-time processing and communication tasks.

Why Choose This Part

This MCU provides a robust 300MHz clock speed and an integrated Floating Point Unit (FPU), making it ideal for math-intensive algorithms. The inclusion of hardware Error Code Correction (ECC) on memory and dual CAN-FD interfaces ensures high reliability and data integrity in harsh electromagnetic environments.

Applications

Automotive Infotainment and Telematics
Utilizes the MediaLB and Ethernet AVB support for low-latency multimedia networking and vehicle data management.
Industrial Gateway Systems
Leverages dual CAN-FD and high-speed USB for bridging multiple communication protocols in factory automation environments.
Motor Control and Power Conversion
Employs the 300MHz FPU-enabled core and PWM peripherals for high-precision control of complex brushless DC motor systems.
Digital Audio Processing
Uses the I2S and SSC interfaces alongside DSP instructions for real-time audio filtering, mixing, and processing.
