Monheim am Rhein, Germany—March 18, 2025

SEGGER announces the release of embOS-Ultra-MPU, the next-generation real-time operating system (RTOS) that builds on the proven foundations of embOS-Classic-MPU and embOS-Ultra.

It combines the precision and power-saving benefits of embOS-Ultra with enhanced memory protection, safety, and system reliability for embedded applications. With its Cycle-Resolution Timing, embOS-Ultra-MPU allows for precise control of timeouts in application programs, making it particularly well-suited for time-sensitive tasks in safety-critical systems.

embOS-Ultra-MPU uses a hardware-based memory protection unit (MPU) to isolate tasks, ensuring that they do not access unauthorised memory regions. This isolation prevents a fault in one task from affecting the entire system.

“embOS-Ultra-MPU is unique. It combines a proven API with zero-interrupt latency, Cycle-Resolution Timing, and robust memory protection,” says Rolf Segger, founder of SEGGER. “In the event of faults or malicious activity, critical system components remain unaffected. This makes it the perfect choice for the medical, automotive, and industrial-control industries.”

embOS-Ultra-MPU is fully compatible with any microcontroller that includes an MPU.
