Renesas Advanced Family provides a high level of security, wide range of connectivity, low power consumption and scalability


Farnell, the Development Distributor, announces the availability of the RA Family of 32-bit Arm® Cortex®-M based MCUs from Renesas Electronics Corporation. This major product introduction will offer design engineers the flexibility to leverage Renesas’ ready to use partner solutions and Arm ecosystem whilst developing their own hardware and software solutions.

The RA MCUs include the advanced high-quality feature set that customers have come to expect from Renesas, with a special focus on security, connectivity and low power. They enable customers to deliver advanced solutions for a wide range of Internet of Things (IoT) applications, including industrial automation, cloud computing and IoT, building automation, smart environment, energy and metering, and home appliances.

All RA MCUs have been designed with a common DNA, making them feature-, software- and pin-compatible for easy scalability and code reuse from one device to another. It is now easy to develop IoT edge and endpoint devices, using the new Flexible Software Package (FSP), fast-start software for security and connectivity, and development tools from Renesas and the Arm partner ecosystem.

The RA MCUs deliver key advantages for design engineers such as market-leading embedded security, superior CoreMark® performance, and ultra-low power operation. Arm PSA security certification provides customers with the confidence and assurance to quickly deploy secure IoT endpoint and edge devices, and smart factory equipment for Industry 4.0.

Products now available from Farnell include:
