Since 1992, embOS has been the preferred RTOS choice for engineers in the embedded market. It offers ease-of-use and guarantees 100% deterministic real-time operation for any embedded device. This real-time operating system is highly portable and fully source-compatible on all platforms, making it easy to port applications to different cores. Tasks can easily be created and safely communicate with each other, using communication mechanisms such as semaphores, mailboxes, and events.
embOS certification & royalties
Certified by TÜV SÜD, embOS complies with the functional safety standards: IEC 61508 SIL 3 and IEC 62304 Class C.
The real-time operating system is free for any non-commercial use like education and evaluation, without any technical limitation.
For commercial use SEGGER offers a versatile embOS licensing policy with no royalties at a reasonable price.
embOS is already deployed on several billion devices. The embedded RTOS is also certified for functional safety in accordance with IEC 61508 SIL 3 and IEC 62304 Class C.
embOS is a high-performance real-time operating system. It has been optimized for minimum memory consumption in both RAM and ROM.
embOS supports virtually any core and compiler by more than 80 embOS ports, including over 500 board support packages for the embedded market.
The leading real-time operating system
From battery-powered, single-chip products to high-end systems: The embOS RTOS is used in different target markets including industrial controls, IoT (Internet of Things), networking, consumer electronics, safety critical devices, automotive to medical devices and avionic. This makes it the market-leading RTOS in the embedded industry.
The next generation RTOS
Using SEGGER's innovative Cycle-based Scheduling, embOS-Ultra is the first choice for applications requiring ultra low power or extremely high precision. Its time resolution is based on the CPU cycle and provides the highest precision possible. Removing iterative scheduler calls from the kernel reduces the energy consumption significantly.
Comprehensive memory protection
embOS-MPU uses the hardware's memory protection unit and additional implemented software mechanisms to prevent one task from affecting the entire system. This guarantees that even if a bug occurs in one task, all other tasks and the operating system itself continue their execution, enhancing both the stability and safety of embedded applications.
Certified RTOS for functional safety
TÜV Süd Germany has certified the RTOS embOS according to IEC 61508 SIL 3 and IEC 62304 Class C. embOS-Safe provides a pre-certified component which simplifies any certification process on the customer side. As a result, embOS-Safe is perfectly suited for being the fundamental component of safety products.
The versatile nature of embOS makes this RTOS a core ingredient of any firmware that has to handle tasks requiring synchronization, timely responses, multiple tasks or threads at the same time. This means it is applied in a wide range of different areas, as seen below. For example, IP stacks and USB-Host side stacks are nearly impossible to run without proper scheduling provided by an RTOS.
Products benefit from certified functional safety thanks to embOS-Safe. Certification is in accordance with IEC 61508 SIL 3 and IEC 62304 Class C.
Internet of Things
embOS is designed for ultra low power consumption. It can be used in any battery-powered application.
embOS is designed for the usage in any networking device. This makes embOS and emNet (TCP/IP stack) the perfect solutions for networking products.
embOS – The first choice of any consumer electronics device. Entertainment, communications or white goods (washing machines, etc.).
embOS is an essential component of every industrial control – especially in applications where functional safety and deterministic behavior are mandatory.
embOS is the perfect real-time operating system for your automotive environment whether it is used inside an ECU or for dashboard applications.
embOS-Safe is the ideal solution for every medical device. The embOS certification according to IEC 62304 Class C ensures the safety of medical products.
Engineers building aerospace systems know that they can rely on the certified embOS-Safe for the foundation of their safety critical products.

The real-time operating system (RTOS) embOS can be delivered as object code or source code package. The source code package extends the object code package by including the embOS source code. Using embOS source code enables the use of application specific compiler options. Compile time switches allow for customization of embOS by enabling only required functionalities. Adding embOS source code to the project provides additional insight when debugging at source-level.
Both embOS packages include the same ready-to-go board support packages for various devices and evaluation boards.
