概要

Description

The ATSAMV71N21B-AAB is Microchip/Atmel’s high‑performance 32‑bit MCU in the SAM V71 family. It uses an ARM Cortex‑M7 core with FPU and DSP features, typically running up to about 300 MHz for strong real‑time performance in control, networking, and signal processing tasks. It combines substantial on‑chip Flash and RAM with flexible external memory interfaces, and a rich peripheral set that suits automotive and industrial applications.
Key peripherals typically include UART/SPI/I2C, USB (FS/HS), Ethernet MAC, CAN FD, DMA, multiple timers, ADCs and DACs, and a hardware crypto engine with RNG for security. The device also provides memory protection and caches to improve deterministic behavior.
The N21B suffix denotes a specific memory map, package type, and industrial temperature variant of the device. Common use cases: automotive/industrial controllers, motor drives, networked embedded systems, and human‑machine interfaces. Development is supported by Microchip’s MPLAB X, Harmony, and Atmel Studio toolchains.

Features
