Overview

The ATSAMD51P20A-AFT is a high-performance 32-bit microcontroller based on the ARM Cortex-M4F processor with a floating-point unit (FPU), running at speeds up to 120MHz. This device features 1MB of Flash memory and 256KB of RAM, providing ample resources for complex embedded algorithms and large data buffers. It is housed in a 128-TQFP package and includes a rich set of peripherals such as QSPI, dual 12-bit DACs, and a 32-channel 12-bit ADC.

Why Choose This Part

This MCU offers a compelling balance of high-speed processing and extensive I/O capability with 99 pins available. The inclusion of a hardware FPU significantly accelerates mathematical computations, while the 256KB RAM supports memory-intensive communication stacks and RTOS environments.

Applications

Industrial Automation
Utilizes the 120MHz clock speed and hardware floating-point support for real-time control loops and sensor fusion in factory equipment.
Advanced HMI Systems
Leverages the large internal SRAM and QSPI interface to drive graphical user interfaces and manage display buffers.
Data Logging and Storage
The integrated MMC/SD controller and 1MB of Flash facilitate high-speed data acquisition and local storage applications.
Digital Signal Processing
The Cortex-M4F core provides dedicated DSP instructions and an FPU for efficient processing of audio and sensor data.
