embOS – Real-Time Operating System (RTOS)

The World-Leading Real-Time Operating System for Embedded Systems

embos RTOS & Embedded Software Solutions
embos-ultra RTOS & Embedded Software Solutions


The heart of every IoT project

embOS is a priority-controlled real-time operating system (RTOS), designed to be used as a foundation for the development of embedded real-time applications. It is a zero interrupt latency, high-performance RTOS that has been optimized for minimum memory consumption in both RAM and ROM, as well as high speed and versatility.


The next generation RTOS

embOS-Ultra is a priority-controlled RTOS (real-time operating system) using SEGGER’s new innovative Cycle-based Scheduling. It offers higher precision and time resolution than any other RTOS on the market, resulting in less energy consumption and a reduced performance hit.

embos safe


The heart of every safety-critical IoT device

embOS-MPU offers memory protection on top of the proven real-time operating system embOS. It significantly enhances both stability and safety for your embedded applications and thereby simplifies any certification process. The operating system and all tasks deemed privileged are memory protected and isolated from any ill effects of unprivileged tasks within your embedded system.


Safety certified real-time operating system

embOS is a certified real-time operating system (RTOS) according to IEC 61508 SIL 3, IEC 62304 Class C, and also 26262. embOS-Safe comes with a certification kit containing all necessary documents, including the comprehensive embOS Safety manual.

Core Libraries – Middleware

Professional Function Libraries for Embedded Systems

emfile RTOS & Embedded Software Solutions
emwin RTOS & Embedded Software Solutions


Reliable Data Storage for your IoT Device

emFile is a file system for embedded applications that can be used on any media for which basic hardware access functions can be provided.


Visualize Your Ideas

emWin is designed to provide an efficient, processor- and LCD controller-independent graphical user interface (GUI) for any application that operates with a graphical LCD.

emlib RTOS & Embedded Software Solutions


Make Software Updates of Your IoT Device Easy

emLoad allows straightforward updates of embedded applications either with a USB Stick, with an SD Card or via USB-Connection to a PC – or else via a serial connection (type RS-232, RS-485).


Data confidentiality & integrity

emLib is a collection of data confidentiality and integrity algorithms which are easily deployed into an embedded system. AES and DES encrypt and decrypt data at rest or in flight, assuring confidentiality. CRC identifies errors in received or stored data, but does not correct them. ECC identifies and corrects common errors in transmitted or stored data, ensuring data integrity.

Compression – Middleware

Highly efficient embedded compression libraries



Save ROM to Save Money

emCompress is a compression system that is able to reduce the storage requirements of data that must be embedded into an application. Compress on the host in advance, decompress in the target on demand.

Connectivity – Middleware

Efficient Software for Embedded Devices



Efficient file transfer for IoT devices

emFTP is the ideal software solution for exchanging files via the FTP protocol. Edge devices can easily transfer their collected data to a server or provide them as a service via FTP.


Add industry standard protocols to IoT devices

emModbus is SEGGER’s implementation of the Modbus protocol. It supports communication via UART (ASCII, RTU) and Ethernet (Modbus/TCP and Modbus/UDP). It is capable of communicating with any Modbus compliant device.



Full Support for IoT Protocol

emMQTT is an MQTT client that uses the socket interface. It can be used with any IP stack supporting the socket interface (such as emNet).


Ideal for any network application

emNet is a high-performance TCP/IP stack that has been optimized for speed, versatility and a small memory footprint. It is written for ANSI C and can be used on virtually any CPU.

emusb-host RTOS & Embedded Software Solutions


Boost your connectivity

emUSB-Device is a high-speed USB-device software specifically designed for embedded systems. Written in ANSI C, it can run on any platform. A wide variety of target drivers are readily available.


Enhance IoT devices through the use of USB Host:

emUSB-Host implements full USB host functionality. This includes external hub support and provides the option for device class drivers. It enables developers to easily add USB host functionality to embedded systems.
