Architected for Performance, Power Efficiency and Ease-of-Use

Two decades of Atmel microcontroller (MCU) leadership and innovation includes many industry-firsts: the first Flash MCU, the first ARM7™-based 32-bit Flash MCU, the first 100nA MCU with RAM retention, and the first ARM9™-based Flash MCU. Atmel continues to leverage this experience to build solutions that help you bring to market smart and innovative products. These innovations inlcude Atmel® | SMART Flash-based products based on the ARM® Cortex®M0+, Cortex-M3, Cortex-M4 and the latest generation Cortex-M7 architectures. These devices range from 8KB to 2MB of Flash and include a rich peripheral and feature mix.

In addition to Flash-based MCUs, Atmel offers Atmel | SMART ARM-based microprocessors (MPUs) that do not have on-board Flash memory. These MPUs include ARM Cortex-A5-based products such as the Atmel | SMART SAMA5 series as well as ARM926EJ-S™-based products such as the Atmel | SMART SAM9261 and SAM9-5 series.

  • Flexible, highly integrated ARM-based MCUs are designed to optimize system control, user interface management, and ease-of-use. The ARM Cortex-M3- and M4-based devices share a single integrated development platform (IDP)—Atmel® Studio 6. This platform provides time-saving source code with more than 1600 example projects, access to debuggers and simulators, integration with Atmel QTouch® technologies for capacitive touch applications, and access to the Atmel Gallery online Apps Store for embedded software and extensions.
  • Atmel ARM-based MPUs range from entry-level devices to advance highly integrated devices with extensive connectivity, refined interfaces, and ironclad security. Atmel provides a full range of hardware and software tools for our ARM-based MPUs to make your design process easier and reduce time to market. Atmel also works with a worldwide network of partners to deliver additional hardware and software solutions for these devices.

In order to optimize and simplify the embedded design process Atmel has built a robust ecosystem around our MCU and MPU. This enables you to complete your projects more easily and get new products to market quickly. Atmel provides a wide range of software tools and embedded software that support leading operating systems. Atmel Studio 6 enables you to get fast results with Atmel MCU devices. You can program and debug Atmel MPUs with familiar third-party tools in conjunction with Atmel in-circuit emulators (ICE).

Key Features

  • Atmel ARM-based Flash MCUs - ARM Cortex-M4, Cortex-M3, Cortex-M0+, ARM926EJ-S™ and ARM7TDMI based Flash MCUs offer:
    • From 8KB of Flash and 4KB of SRAM up to 2MB of Flash memory and 160KB of SRAM, with operating frequencies up to 120MHz
    • Innovative direct memory access (DMA) and memory implementations, which enable high-speed data transfers while freeing the processor for the application
    • "Touch-ready" capability through Atmel Qtouch capacitive touch technology with hardware acceleration in the SAM C and SAM D family
    • Serial communication module (SERCOM), available in the Atmel | SMART SAM D series, is fully software-configurable to handle I2C, USART/UART, and SPI communications to enhance interface flexibility. The SAM C series adds RS485 and LIN-interfaces to SERCOM modules as well
    • The lowest power consumption available in an ARM Cortex-M4-based MCU
  • Atmel ARM-based embedded MPUs - ARM Cortex-A5 and ARM926EJ-S™ based embedded MPUs are easy to use and ideal for cost-sensitive applications. They offer:
    • Performance up to 945DMIPS at 600MHz with a floating point unit (FPU) and ARM Neon technology for accelerated data processing and precision
    • Market-leading power consumption at less than 150 mW when running at maximum speed, and less than 200uW in Low Power mode
    • Powerful peripherals including High-Speed USB host and device, Gigabit Ethernet, CAN, TFT LCD controller, camera interface, and more
    • Robust security thanks to hardware crypto engine, secure boot, external DDR encryption, secure storage, tamper pins, environmental monitors, ARM Trust Zone and more
    • Free Linux and Android distributions and a comprehensive partner ecosystem to provide additional hardware and software solutions
