Overview

The ATSAME53J20A-AZ-SL3 is a high-performance 32-bit microcontroller based on the ARM Cortex-M4F processor with a floating-point unit, running at speeds up to 120MHz. It features 1MB of Flash and 256KB of RAM, integrated with an Ethernet MAC and dual CAN-FD interfaces for robust communication. This variant is designed for extended temperature environments and comes in a 64-pin TQFP package.

Why Choose This Part

The SAM E53 series offers a unique combination of high-speed connectivity (Ethernet and USB) with a large 256KB SRAM, allowing for complex networking stacks and data buffering. Its wide operating voltage of 1.71V to 3.63V and extended temperature support make it reliable for harsh industrial power environments.

Applications

Industrial Gateway
Utilizing the integrated Ethernet and multiple serial interfaces to bridge industrial fieldbus protocols to Ethernet networks.
Secure IoT Endpoints
Leveraging the hardware-based security features and high memory density for encrypted cloud connectivity and firmware-over-the-air updates.
Motor Control Systems
Using the 120MHz Cortex-M4F core and advanced PWM peripherals for precise control of industrial motor drives.

Getting Started

Develop using the MPLAB X IDE or Atmel Studio 7 along with the MPLAB Harmony v3 software framework for driver and middleware support. Hardware evaluation can be performed using the SAME53 Curiosity Nano or the SAM E54 Xplained Pro evaluation kits which share the same core architecture.

Also Consider

STM32F407VGT6 STMicroelectronics - Offers similar Cortex-M4F performance with integrated Ethernet but in a different ecosystem and peripheral set.
ATSAME54P20A MCHPMicrochip Technology - Provides the same core and memory but adds CAN-FD support and higher pin count for more complex I/O requirements.
Tiva C Series TM4C1294 TITexas Instruments - Features an integrated Ethernet PHY alongside the MAC, reducing the total BOM for networked industrial applications.
