Overview

The ATSAME51J20A-AU is a high-performance 32-bit microcontroller based on the Arm Cortex-M4F core with a floating-point unit (FPU), running at speeds up to 120MHz. It features 1MB of Flash with Error Correction Code (ECC) and 256KB of SRAM, making it suitable for demanding industrial and automotive applications. This MCU integrates a rich set of peripherals including Dual CAN-FD interfaces, a 10/100 Ethernet MAC, and a QSPI interface for external memory expansion.

Why Choose This Part

The SAM E51 series stands out by combining a 403 CoreMark performance rating with advanced power management features like SleepWalking peripherals and a 1.2V integrated buck regulator. Its SmartEEPROM technology provides hardware-emulated EEPROM functionality with endurance far exceeding standard Flash, while the ECC-protected memory ensures high reliability in electrically noisy environments.

Applications

Industrial Automation
Utilizes the integrated CAN-FD and Ethernet interfaces for robust communication in PLC and factory control systems.
Automotive Gateways
Serves as a high-speed bridge between vehicle networks thanks to its dual CAN-FD controllers and extensive serial connectivity.
Solar Inverters
Leverages the 120MHz Cortex-M4F core and high-speed 12-bit ADCs for real-time power conversion and monitoring.
Secure IoT Edge Nodes
Employs hardware AES and SHA crypto engines alongside Public Key Cryptography to secure networked sensor data.
