Renesas Electronics has introduced the world’s most powerful microcontrollers (MCUs), delivering breakthrough performance of over 3000 CoreMark points, and fully deterministic, low latency, real-time operation that satisfies customers’ most demanding application needs.

The new RA8 Series MCUs are the industry’s first to implement the Arm Cortex-M85 processor, enabling the new devices to deliver industry-leading 6.39 CoreMark/MHz performance. This level of performance will allow system designers to use the RA MCUs in applications that previously required microprocessors (MPUs). The new series is part of Renesas’ popular RA Family of MCUs based on Arm Cortex processors. Existing designs built for other RA devices can easily be ported to the new RA8 MCUs.

Helium technology for superior AI performance

The new RA8 Series MCUs deploy Arm Helium technology, Arm’s M-Profile Vector Extension that provides a 4X performance boost for digital signal processor (DSP) and machine learning (ML) implementations versus MCUs based on the Arm Cortex-M7 processor. This performance uplift can enable customers to eliminate an additional DSP in their systems for certain applications.

Renesas demonstrated the performance uplift with Helium technology at Embedded World 2023, with its very first silicon. Renesas is a leader in AI for the edge and endpoint with a wide range of embedded AI and TinyML solutions for advanced applications in automotive, industrial and commercial products based on its Reality AI Tools, as well as an extensive portfolio of embedded processing and IoT offerings.

The new RA8 Series MCUs enable edge and endpoint devices to implement natural language processing in voice AI and predictive maintenance applications, using Helium to accelerate the neural network processing.

- We’re proud to introduce the new RA8 Series with the powerful Arm Cortex-M85 processor. As the world’s MCU leader, our customers expect leading-edge performance and functionality from Renesas, says Roger Wendelken, Senior Vice President and Head of the MCU Business at Renesas.

- They also rely on us to help them navigate new trends and technical challenges. The RA8 Series sets a new bar for MCU performance and features and will ease the implementation of AI in a huge array of new applications.

- The advent of AI is increasing demand for intelligence at the edge and endpoints to serve new applications across diverse markets including industrial automation, smart home, and medical, adds Paul Williamson, Senior Vice President and General Manager, IoT Line of Business, Arm.

- Renesas’ new MCUs, built on Arm’s highest-performing and most secure Cortex-M processor to date, are specifically optimized for signal processing and ML workloads, and will be game-changing for innovators looking to address the growing AI opportunities in the embedded and IoT space, without compromising on security.

Leading security features

In addition to leading performance, RA8 Series MCUs offer advanced, leading-edge security. The Cortex-M85 core includes Arm TrustZone technology which enables isolation and secure/non-secure partitioning of memory, peripherals and code.

The RA8 Series MCUs introduce the most advanced Renesas Security IP (RSIP-E51A) that provides leading edge cryptographic accelerators and supports a true secure boot. Other advanced security features include immutable storage for a strong hardware Root-of-Trust, Octal SPI with Decryption-on-the-fly (DOTF), secure authenticated debug, secure factory programming and tamper protection.

In concert with Arm TrustZone, this enables comprehensive and fully integrated secure element functionality. The Armv8.1-M architecture introduces Pointer Authentication and Branch Target Identification (PACBTI) security extension that provides mitigation for software attacks targeting memory safety violations and memory corruptions. The RA8 Series also targets PSA Certified Level 2 + Secure Element (SE), NIST CAVP and FIPS 140-3 certifications.

Low power features

RA8 Series devices integrate new low power features and multiple low power modes to improve power efficiency, even while providing industry-leading performance. A combination of low power modes, independent power domains, lower voltage range, fast wakeup time and low typical active and standby currents enables lower overall system power and allows customers to meet regulatory requirements. The new Arm Cortex-M85 core also performs various DSP/ML tasks at much lower power.

Renesas has begun volume shipments of the first devices in the RA8 Series, the RA8M1 Group. RA8M1 Group MCUs are general-purpose devices that address diverse compute intensive applications in industrial automation, home appliances, smart home, consumer, building/home automation, medical and AI in applications such as fingerprint scanners, thermostats, PLC, smart meters and home hubs.
