SAM 4L MCUs

Redefining Low Power in ARM® Cortex® M4 based Microcontrollers

SAM4L microcontrollers (MCUs) redefine the power benchmark for Cortex®-M4 processor-based devices, delivering the lowest power in active mode (down to 90µA/MHz) as well as sleep mode with full RAM retention (1.5µA) with the shortest wake-up time (down to 1.5µs). Embedding Microchip picoPower® technology, the SAM4L family provides highly efficient signal processing, ease of use and high-speed communication peripherals—ideal for power-sensitive designs in the industrial, healthcare and consumer application areas.

Microchip 32-bit Framework

Advanced Software Framework

The Advanced Software Framework (ASF) is a MCU software library providing a large collection of embedded software for Atmel flash MCUs: megaAVR, AVR XMEGA, AVR UC3 and SAM devices.

  • It simplifies the usage of microcontrollers, providing an abstraction to the hardware and high-value middlewares
  • ASF is designed to be used for evaluation, prototyping, design and production phases
  • ASF is integrated in the Atmel Studio IDE with a graphical user interface or available as standalone for GCC, IAR compilers
  • ASF can be downloaded for free

For more information visit the Advanced Software Framework page.

Atmel START

Atmel® START is an innovative online tool for intuitive, graphical configuration of embedded software projects. It lets you select and configure software components, drivers and middleware, as well as complete example projects, specifically tailored to the needs of your application. The configuration stage lets you review dependencies between software components, conflicts and hardware constraints. In the case of a conflict, Atmel START will automatically suggest solutions that fit you specific setup.
