Micrium is a global RTOS leader and a top choice of embedded engineers building microprocessor, microcontroller, and DSP-based devices. In addition to its microkernels, Micrium provides communication components including TCP/IP, USB and Modbus protocol stacks and a CAN protocol framework. Also available are storage and display components and the visualization tool uC/Probe.

The uC/OS-II/uC/OS-III RTOS awareness plug-in for C-SPY is generic and works with any target processor.


Highly portable, ROMable, scalable, preemptive, real-time, deterministic, multitasking kernel for microprocessors, microcontrollers and DSPs. Allows for unlimited tasks, semaphores, mutexes, event flags, message queues, timers and memory partitions.


Portable, ROMable, scalable, preemptive, real-time deterministic multitasking kernel for microprocessors, microcontrollers and DSPs.


Memory and time management for safety-critical systems. Allows you to get certification for complex systems affordably. Extends the capabilities of existing safety-critical products with non-safety critical complex middleware such as TCP-IP, file systems, and USB.


Extension for µC/OS-III. Provides memory protection.

Per-seat licensing

Micrium's Per Seat License is available for µC/OS-II and µC/OS-III, as well as most of Micrium's middleware products, including USB and TCP/IP stacks. Created to align with the licensing model used by IAR Systems, this license model allows one engineer full product access for any number of projects.
