FreeRTOS™ Real-time operating system for microcontrollers

Developed in partnership with the world’s leading chip companies over an 18-year period, and now downloaded every 170 seconds, FreeRTOS is a market-leading real-time operating system (RTOS) for microcontrollers and small microprocessors. Distributed freely under the MIT open source license, FreeRTOS includes a kernel and a growing set of IoT libraries suitable for use across all industry sectors. FreeRTOS is built with an emphasis on reliability and ease of use.

Why FreeRTOS?

  • Trusted kernel

    With proven robustness, tiny footprint, and wide device support, the FreeRTOS kernel is trusted by world-leading companies as the de facto standard for microcontrollers and small microprocessors.

  • Accelerate time to market

    With detailed pre-configured demos and Internet of Things (IoT) reference integrations, there is no need to determine how to setup a project. Quickly download, compile, and get to market faster.

  • Broad ecosystem support

    Our partner ecosystem provides a breadth of options including community contributions, professional support, as well as integrated IDE and productivity tools.

  • Predictability of long term support

    FreeRTOS offers feature stability with long term support (LTS) releases. FreeRTOS LTS libraries come with security updates and critical bug fixes for two years. Maintained by AWS for the benefit of the FreeRTOS community.

Features

Tiny, power-saving kernel

Scalable size, with usable program memory footprint as low as 9KB. Some architectures include a tick-less power saving mode

Support for 40+ architectures

One code base for 40+ MCU architectures and 15+ toolchains, including the latest RISC-V and ARMv8-M (Arm Cortex-M33) microcontrollers

Modular libraries

A growing number of add-on libraries used across all industry sectors, including secure local or cloud connectivity

AWS Reference Integrations

Take advantage of tested examples that include all the libraries essential to securely connect to the cloud

MIT licensed, with options

FreeRTOS can be used for any purpose under its MIT license. Our strategic partner also provides commercial licenses, and safety certification.

  • Delta Over-the-Air Updates

    The ability to update device software Over-the-Air (OTA) is becoming increasingly important as more embedded devices get connected to the cloud. OTA updates enable operators to apply security fixes and add new features to already deployed devices, at scale, quickly and reliably, and without requiring an expensive or impractical technician visit. While OTA benefits all […]

  • What's New in November 2021 FreeRTOS Releases

    We're excited to share these latest updates: The FreeRTOS download now contains an example of code that demonstrates a method of minimizing the time that an application spends in privileged mode in FreeRTOS ports on microcontrollers (MCUs) with Memory Protection Unit (MPU) support. These FreeRTOS ports with MPU support enable MCU applications to be more […]
