Overview

The ATSAMD51J19A-MFT is a high-performance 120MHz ARM Cortex-M4F microcontroller featuring a Floating Point Unit (FPU) and integrated hardware cryptography. It provides 512KB of Flash and 192KB of SRAM, making it well-suited for demanding processing tasks that require real-time math and secure connectivity.

Why Choose This Part

This MCU offers a powerful combination of a 120MHz M4F core and a large 192KB SRAM buffer for handling high-bandwidth data streams. Its versatile SERCOM modules can be software-configured as I2C, SPI, or USART, providing exceptional routing flexibility on dense PCB designs.

Applications

Industrial Control Systems
Utilizes the 120MHz clock speed and multiple SERCOM interfaces for complex automation logic and industrial networking.
Brushless DC Motor Control
Leverages the Cortex-M4F FPU and dedicated PWM peripherals for precise field-oriented control (FOC) algorithms.
Secure IoT Gateways
Integrates hardware-accelerated security features and USB connectivity for bridging local sensor networks to the cloud.
Professional Audio Equipment
Uses the I2S interface and high-speed data converters for digital audio processing and playback.
