Description
The RA8M2 group features 32-bit general-purpose MCUs that combine 1GHz Arm® Cortex®-M85 with Helium™ Vector Extensions and 250MHz Cortex-M33 cores, delivering over 7300 CoreMark CPU performance to meet demanding application needs. These MCUs are ideal for compute-intensive applications in industrial automation, home appliances, smart home, consumer, building/home automation, and medical/healthcare market segments.
RA8M2 MCUs integrate large on-chip MRAM and SRAM memory, multiple memory interfaces, and a rich peripheral set, enabling efficient system design and lower costs. The MRAM provides non-volatile, high-reliability storage for critical data. Available in packages from 176 to 303 pins with junction temperature up to 125°C, these MCUs enable a wide range of industrial and IoT/consumer applications. Secure Element-like functionality is built-in, with advanced cryptographic security IP, immutable storage, and tamper protection, to ensure data privacy and integrity.
The RA8M2 MCUs are fully supported by the Flexible Software Package and a comprehensive set of hardware and software development tools.
