The RA8M1 MCU Group features the industry’s first 32-bit microcontrollers (MCU) based on the Arm® Cortex®-M85 (CM85) core, delivering breakthrough performance of over 3000 CoreMark points at 480 MHz, with fully deterministic, low latency, real-time operation that enables customers’ most demanding application needs. These are general-purpose MCU devices and address diverse high-performance and compute-intensive applications in Industrial Automation, Home Appliances, Smart Home, Consumer, Building/Home Automation and Medical/Healthcare market segments.

The RA8M1 MCUs integrate the high-performance CM85 core with large memory, multiple external interfaces, and a rich peripheral set optimized to address diverse application requirements, and are available in packages from 100 pins to 224 pins, to serve the needs of a broad range of high-performance applications. Secure Element-like functionality is built-in with advanced cryptographic Security IP, immutable storage, and tamper protection, for truly secure IoT.

The RA8M1 MCUs are fully supported by the Flexible Software Package and a comprehensive set of hardware and software development tools.
