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

Atmel's two decades of 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. We continue to leverage this experience to build solutions that help you bring to market smart and innovative products. Atmel now offers Flash- based ARM® products based on the ARM Cortex®-M0+, Cortex-M3 and Cortex-M4 architectures, ranging from 8KB to 2MB of Flash including a rich peripheral and feature mix.

In addition to ARM-based MCU products, Atmel offers ARM-based microprocessors (MPUs) that do not have on-board Flash memory. These MPUs include ARM Cortex®-A5-based products such as the ARM926EJ-S™-based Atmel® SAMA5D3 and AT91SAM9261 devices.

  • Flexible, highly integrated Atmel 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/simulators, integration with Atmel QTouch® tools 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 we have built a robust ecosystem around our microcontrollers and microprocessors. 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 D family
    • Serial communication module (SERCOM), available in the SAM D series, is fully software-configurable to handle I2C, USART/UART and SPI communications to enhance interface flexibility
    • 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 850DMIPS at 536MHz with a floating point unit
    • Market-leading power consumption at less than 200mW when running at maximum speed
    • Powerful peripherals including USB high-speed host and device, Gigabit Ethernet, CAN, TFT LCD controller, camera interface and more
    • Robust security thanks to hardware crypto engine and secure boot
    • Free Linux and Android distributions and a comprehensive partner ecosystem to provide additional hardware and software solutions
