Overview

The ATSAM4E16EA-AU is a high-performance 120 MHz ARM Cortex-M4 microcontroller featuring a Floating Point Unit (FPU) and a robust set of connectivity interfaces. It integrates 1024KB of Flash and 128KB of SRAM, making it well-suited for applications requiring complex math processing and industrial-grade networking. The device includes specialized hardware for error correction and high-speed data movement without CPU intervention.

Why Choose This Part

This MCU offers a unique combination of high-resolution 16-bit analog peripherals and comprehensive networking suites including Ethernet, USB, and CAN. The zero-latency peripheral performance and dedicated 2KB cache ensure predictable real-time execution for safety-critical tasks.

Applications

Industrial Automation Gateways
Utilizes integrated Ethernet and dual CAN 2.0B controllers to bridge factory floor protocols and enterprise networks.
Precision Instrumentation
Leverages the 16-bit ADC resolution with offset and gain error correction for high-accuracy sensor data acquisition.
Professional Audio Equipment
Employs the Cortex-M4 FPU and 120 MHz clock speed for real-time digital signal processing and audio stream management.
Energy Management Systems
Monitors multiple power phases using 24 ADC channels while communicating via the External Bus Interface (EBI) to large graphical displays.

Getting Started

Develop using Microchip Studio or MPLAB X IDE with the XC32 compiler. For hardware evaluation, the SAM4E-XPRO evaluation kit provides access to all I/O and integrated Ethernet PHY testing. Practical firmware development is supported by the Advanced Software Framework (ASF) which includes drivers for the 16-bit ADC and networking stacks.
