Remote MCU Development Toolchain Integration

MIKROE and Renesas Electronics Corporation have established a multi-year cooperation to integrate development tool support for a broad range of Renesas microcontrollers, combined with remote access to physical evaluation hardware for embedded software development.

Context of the Cooperation
MIKROE is a supplier of embedded hardware and software development tools, including integrated development environments, add-on boards, and open hardware standards. Renesas Electronics Corporation develops microcontrollers and processors for industrial, automotive, and infrastructure applications.

The cooperation addresses a recurring challenge in embedded system development: the delay between the announcement of new microcontroller units (MCUs) and practical access to evaluation hardware. For complex MCU portfolios, toolchain readiness, hardware availability, and peripheral support often limit early software development. The agreement combines Renesas’ MCU portfolio with MIKROE’s development infrastructure to reduce these constraints.

Technical Solution and Responsibilities
Under the agreement, MIKROE provides development tool support for approximately 500 Renesas MCUs, with additional devices added as new products are released. Tool support is implemented through MIKROE’s NECTO multi-architectural integrated development environment, which enables code editing, compilation, programming, and debugging across supported architectures.

Hardware expansion and peripheral evaluation are handled through Click Board™ add-on modules, which interface via the open mikroBUS™ socket standard. This allows reuse across multiple host platforms supporting the same interface. Software integration is supported through open-source mikroSDK libraries, enabling direct access to peripherals and simplifying driver-level development.

Deployment and Remote Infrastructure
A key element of the cooperation is the deployment of a remote hardware access platform, known as the Planet Debug board farm. The infrastructure consists of physical Renesas evaluation boards connected via network-enabled debugging hardware. Developers can reserve time on these systems and perform programming and debugging remotely using NECTO Studio, without local hardware installation.

Remote access is enabled by Wi-Fi–based programming and debugging hardware, allowing real-time interaction with physical boards rather than simulation. The board farms are deployed across multiple regions, including Europe and the Americas, and are operated and maintained by MIKROE.

Applications and Use Cases
The solution targets embedded development in industrial automation, smart building systems, consumer electronics, and infrastructure control. Typical use cases include early firmware development for new MCU families, peripheral evaluation, proof-of-concept development, and validation of communication interfaces prior to hardware procurement.

Expected Impact
By aligning toolchain availability with MCU product announcements, the cooperation reduces initial development lead times and hardware sourcing delays. Remote access to standardized evaluation platforms also supports parallel development by distributed engineering teams and lowers entry barriers for early-stage prototyping.
