Renesas to Demonstrate MCU of Arm Processor

Renesas is developing a new series of RA MCUs based on the Cortex-M85 processor, planned for release in 2023.

Renesas Electronics Corporation will be presenting its first live demonstration of a microcontroller (MCU) based on the recently announced Arm® Cortex®-M85 processor.

Renesas MCU ProcessorThe demonstration will take place in the Renesas booth – Hall 1, Stand 234 (1-234) at the Embedded World 2022 Exhibition and Conference in Nuremburg Germany from June 21-24.

Renesas introduced the RA (Renesas Advanced) Family of Arm Cortex-M based MCUs in October of 2019, entering the general-purpose Arm-Cortex-M market with a robust and feature-rich family of flash-based MCUs.

“As a lead partner with Arm, we are proud to be the first to demonstrate an MCU based on the high-performance Cortex-M85 processor, a clear example of the momentum that we have built in the Arm ecosystem,” said Roger Wendelken, Senior Vice President in Renesas’ IoT and Infrastructure Business Unit. “The RA family has enjoyed tremendous success in a very short time, demonstrating the core strengths that make Renesas an MCU powerhouse, including design expertise, legendary quality, and close collaboration with customers and partners in all markets and all geographies.”

“To continue to scale and grow, the next generation of IoT solutions demand ever-improving levels of performance, security and simplified development, and we have delivered this with the new Arm Cortex-M85,” said Dipti Vachani, Senior Vice President and general manager, Automotive and IoT Line of Business at Arm. “This demonstration of the first silicon-based on our most secure and highest performance Cortex-M processor will showcase the new and exciting applications it will enable and further cements our ongoing close collaboration with Renesas.”

Renesas is developing a new series of RA MCUs based on the Cortex-M85 processor, planned for release in 2023.

These new RA family MCUs will provide breakthrough performance and fully deterministic, low latency, real-time operation for demanding application needs across numerous markets.

The new RA devices will bridge the gap between MCUs and MPUs, enabling complex and compute-intensive applications with lower power consumption and ease of use of an MCU.

The new Cortex-M85 core based on Armv8-M architecture supports Arm TrustZone® technology for protection of secure assets.

Combined with TrustZone, Renesas’ integrated cryptographic engine, immutable storage, key management, and tamper protection against DPA/SPA side-channel attacks will provide a comprehensive and fully integrated secure element functionality.
