Overview

The ATSAM3U2CA-CU is a high-performance 32-bit ARM Cortex-M3 microcontroller featuring a high-speed USB 2.0 interface with integrated transceiver. It provides 128KB of Flash and 36KB of SRAM, specifically designed for data-intensive applications requiring fast communication and low latency.

Why Choose This Part

The primary advantage is the integrated High-Speed USB 2.0 peripheral, which is rare in microcontrollers of this class. It also features a dual-bank Flash architecture that supports safe in-application programming (IAP) for seamless firmware updates.

Applications

High-Speed USB Peripherals
Leverages the integrated High-Speed USB 2.0 (480 Mbps) interface for PC peripherals and data acquisition devices.
Industrial Data Loggers
Utilizes the high-speed bus matrix and dual-bank Flash for reliable data storage and field updates.
Sensor Hubs
Collects and processes multi-sensor data using the high-pin-count BGA package and integrated analog-to-digital converters.

Getting Started

Development is supported by the Microchip Studio IDE and the MPLAB X ecosystem. Engineers should use the SAM3U-EK evaluation kit or the J-Link debug probe for hardware development, while utilizing the Atmel Software Framework (ASF) for USB stack implementation.
