Green Hills Software’s March 11, 2025 announcement added automotive and industrial microcontroller profiles to its µ-velOSity RTOS-based software environment. The profiles combine the real-time operating system with middleware, peripheral drivers, development tools and safety evidence, with features aimed at production embedded systems.
What Green Hills added for automotive and industrial microcontrollers
At the center of the environment is µ-velOSity, a compact real-time operating system with a simple API, floating-point unit (FPU) support and memory protection unit (MPU) support. Green Hills describes the new profiles as complete software stacks rather than an RTOS alone: they bring together middleware, peripheral drivers, development tools and safety-related artifacts.
The automotive and industrial profiles add production-oriented components, including:

- Diagnostics over IP (DoIP) for diagnostic communication over IP networks.
- Fail-safe file systems with wear leveling.
- Data Distribution Service (DDS) middleware.
- CDCF and SoC-specific acceleration libraries.
Green Hills positions these components for embedded products where networking, diagnostics, memory management and safety development need to be integrated with the target MCU software.

What the safety certifications do—and do not—establish
In its March 2025 announcement, Green Hills named TÜV NORD certifications to ISO 26262 ASIL D, IEC 61508 SIL 3, EN 50128 SIL 4 and EN 50657 SIL 4. These standards address functional safety in different sectors and use different assurance levels: ISO 26262 is automotive, IEC 61508 is a cross-industry functional-safety standard, and EN 50128 and EN 50657 concern railway software and railway rolling stock software, respectively.
Those named certifications are evidence relevant to safety development; they should not be read as a claim that every µ-velOSity-based product, customer configuration or MCU application is automatically certified. The announcement describes a platform and its safety evidence. A product team still needs to establish that its particular hardware, software configuration, development process and intended use meet the applicable requirements.

How µ-velOSity fits into Green Hills’ toolchain
Green Hills integrates µ-velOSity with its MULTI integrated development environment (IDE), History debugging and trace tool, safety-certified compilers and JTAG/Trace Probe. The environment can also include µ-visor and INTEGRITY for heterogeneous systems-on-chip (SoCs), where different processing elements may need different software environments.

That integration matters when evaluating the platform: compatibility is not just whether the RTOS can run on an MCU. It also includes the compiler and debug workflow, available drivers and middleware, safety artifacts, and how the MCU software interacts with other cores or software on the SoC.

- Maximum performance: the Pro micro microcontroller development board runs at 5 V/16 MHz and supported by IDE V1.0.1 for smooth programming. Suitable for Arduino.
- Versatile connections: Pro micro with 4 x 10-bit ADC pins, 12 x digital I/Os and serial Rx and Tx hardware connections, you have all the ports you need.
- Easy programming: Pro micro simply connect the motherboard to the on-board micro USB port and program it. If it is not detected, just install the driver.
- Multifunctional I/O: Pro micro there are 54 digital input/output pins available, including analogue inputs/outputs, as well as interfaces such as PWM, SPI, I2C etc., which offer a wealth of hardware connection options.
- Good compatibility: the seamless integration with the Arduino IDE and the extensive development tools and libraries ensure a smooth learning curve and make it a good choice for beginners.
Which microcontroller platforms are named
Green Hills’ broader partner announcements identify several current examples. They do not amount to a universal compatibility list for every µ-velOSity component or configuration.
| Platform | What the cited announcement establishes |
|---|---|
| Infineon AURIX TC4x | Infineon and Green Hills announced an AURIX TC4x platform on April 2, 2024. |
| NXP S32 | Green Hills announced participation in NXP S32 CoreRide on April 3, 2024. |
| MIPS Atlas M8500 RISC-V MCU | MIPS and Green Hills announced an M8500 MCU Safety SDK on March 9, 2026. |
For other MCUs, Green Hills says customers should contact a local office about options such as RH850 and TriCore. Confirm support for the exact chip, profile, driver set and toolchain version directly with the vendor before planning a production design.

Automotive cybersecurity is a separate credential
Green Hills separately announced in 2024 that it had received ISO/SAE 21434 automotive cybersecurity certification from exida. That is distinct from the functional-safety certifications named for the MCU environment: cybersecurity process certification does not replace the safety evidence or product-specific work needed for a particular application.
