Key features
embOS is built to empower developers with the tools they need to create efficient, reliable, and scalable embedded systems. Its design reflects decades of refinement, ensuring it meets the diverse requirements of modern applications while remaining adaptable to a broad range of hardware and development environments.
Reliability
Now in its fourth decade, embOS has proven its reliability after being deployed in several billion devices. An edition certified for functional safety in accordance with IEC 61508 SIL 3, IEC 62304 Class C, and ISO 26262 ASIL D is available as well.
Efficiency
embOS is a high-performance real-time operating system. It is a true lightweight RTOS optimized for minimum memory consumption in both RAM and ROM, as well as for high speed and versatility.
Availability
embOS supports virtually any core and compiler, offering more than 100 ports and over 500 board support packages for the embedded market. It integrates seamlessly with all major compilers and embedded development tools, including SEGGER's Embedded Studio.
Use cases
embOS is suitable for a wide range of use cases across a variety of embedded applications. In general, something that all use cases have in common is that they involve one or multiple microcontrollers or processors.
Battery-powered devices
Wherever power is a valuable resource (such as with handheld devices), low-power operation modes should be employed as often as possible. All embOS RTOS editions include features (like tickless RTOS support) to significantly reduce power consumption, and they are tailored to run on even the smallest microcontrollers.
Networking and IoT
Connected networks introduce a variety of tasks that might interfere with the original intended use of the device. All embOS editions provide robust and proven RTOS scheduling and task management functions to ensure safe operation under adverse conditions. This makes embOS an ideal IoT RTOS.
Safety-critical devices
embOS-Safe's functional safety certification is in accordance with IEC 61508 SIL 3, IEC 62304 Class C, and ISO 26262 ASIL D. Certification is achieved without modifications to the backbone, which serves as a foundation for all embOS editions.
Precise and predictable control systems
Closed-loop and other control systems require real-time conditions to operate. embOS warrants deterministic behavior by design, minimizing or even removing RTOS latency and jitter. embOS-Ultra takes precision even further by providing enough headroom for future applications.
Customer voices
"Using SEGGER's products has been a great move for our firmware. SEGGER’s product reliability and support have substantially facilitated our firmware development."
Jason Schlessmann, adidas Wearable Sports Electronics, United States
"I am especially happy about embOS's performance. I have a multitasking application that includes audio; real-time video capture; flash writing; and, at the same time, video dispatches to a remote site through a wireless radio interface. Without embOS, I can hardly imagine how I could do all these tasks."
Jimmy Wang, United States

Cycle-based scheduling with embOS-Ultra
embOS-Ultra reduces CPU usage and conserves energy. Jacob Beningo of Beningo Embedded Group tests the product here and explains the difference between traditional system tick-based RTOS scheduling and SEGGER's embOS-Ultra, which utilizes cycle-based scheduling.
First-class support
SEGGER offers first-class support directly from the embOS embedded experts and development team. Customers can tap into a knowledge base developed over almost four decades. For support requests, this means quick turn-around times as well as responses from qualified experts.
Supported devices
embOS supports virtually all popular microcontrollers and other CPUs. In general, if a core is supported, then all that is needed is a fairly simple board support package — either derived from an existing package, or selected from packages that SEGGER's engineers have already developed.
More details are available under embOS ports, as is a list of included board support packages.
Licensing
The software is available under various embedded software license models and can be delivered as source code. All commercial licenses are based on a one-time payment, are royalty-free, and include six months of updates and support from SEGGER’s Embedded Experts.
There are no subscription fees, ensuring predictable and fixed costs over the entire product lifetime.
For non-commercial use, evaluation, and educational purposes, the software is provided under SEGGER’s Friendly License.
