Renesas RA8M1

The RA8M1 MCU Group features the industry’s first 32-bit general-purpose microcontrollers (MCU) based on the Arm^® Cortex^®-M85 (CM85) core, delivering over 3000 Coremark points at 480 MHz.

The RA8M1 MCUs integrate the CM85 core with large memory, multiple interfaces and peripheral and are available in packages from 100 to 224 pins. Secure Element like functionality is built-in with advanced cryptographic Security IP, immutable storage and tamper protection.

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