Overview

The ATSAME53J19A-AU is a high-performance 32-bit microcontroller featuring an ARM Cortex-M4F core with a Floating Point Unit running at speeds up to 120MHz. This MCU is part of the SAM E53 series, specifically designed for industrial applications requiring integrated Ethernet support and extensive connectivity options within a compact 64-TQFP package. It combines 512KB of Flash and 192KB of RAM with a robust set of peripherals including dual 12-bit ADCs and dual 12-bit DACs.

Why Choose This Part

This MCU provides a powerful upgrade path for Cortex-M0+ or M23 users who require higher math throughput via the M4F core and integrated Ethernet. The inclusion of QSPI allows for easy memory expansion, while the 192KB of SRAM provides a generous buffer for networking stacks and data-heavy applications.

Applications

Industrial Ethernet Gateways
Utilizing the integrated 10/100 Mbps Ethernet MAC to bridge industrial fieldbus protocols to factory networks.
Secure IoT Edge Nodes
The high clock speed and hardware floating point unit enable local data processing and encryption before transmission.
Motor Control Interfaces
Leveraging PWM peripherals and fast 12-bit analog-to-digital converters for precise feedback loops in automation.
Human Machine Interface (HMI)
The 120MHz core and ample RAM support driving small graphical displays and touch interfaces via SPI or QSPI.
