RA8E1 and RA8E2 Deliver Unmatched Scalar and Vector Compute Performance with Best-in-Class Feature Set to Address Value-Oriented Markets

Renesas Electronics Corporation (TSE:6723), a premier supplier of advanced semiconductor solutions, today introduced the RA8E1 and RA8E2 microcontroller (MCU) groups, extending the industry’s most powerful series of MCUs. Introduced in 2023, the RA8 Series MCUs are the first to implement the Arm® Cortex®-M85 processor, enabling them to deliver market-leading 6.39 Coremark/MHz performance. The new RA8E1 and RA8E2 MCUs offer the same performance but with a streamlined feature set that reduces costs, making them excellent candidates for high-volume applications such as industrial and home automation, office equipment, healthcare, and consumer products.

The RA8E1 and RA8E2 MCUs deploy Arm Helium™ technology, Arm’s M-Profile Vector Extension that provides up to 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 enables applications in the fast-growing field of AIoT where high performance is crucial to execute AI models.

RA8 Series devices integrate 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 lower overall system power consumption and meet regulatory requirements. The new Arm Cortex-M85 core also performs various DSP/ML tasks at much lower power.

RA8 Series MCUs are supported by Renesas’ Flexible Software Package (FSP). The FSP enables faster application development by providing all the infrastructure software needed, including multiple RTOS, BSP, peripheral drivers, middleware, connectivity, networking, and TrustZone support as well as reference software to build complex AI, motor control and cloud solutions. It allows customers to integrate their own legacy code and choice of RTOS with FSP, thus providing full flexibility in application development. Using the FSP will ease migration of existing designs to the new RA8 Series devices.

“Our customers love the superior performance of the RA8 MCUs and are now looking for more feature optimized versions combined with high performance for their cost-sensitive industrial, vision AI and mid-end graphics applications,” said Daryl Khoo, Vice President of Embedded Processing 1st Business Division at Renesas. “The RA8E1 and RA8E2 deliver the right balance of performance and features for those markets and, with FSP, enable easy migration within the RA8 Series or from RA6 MCUs.”
