Description
The RA8P1 group features Renesas’s first 32-bit AI-accelerated microcontrollers (MCUs) powered by the high-performance Arm® Cortex®-M85 (CM85) with Helium™ MVE and Ethos™-U55 NPU. It delivers 256GOPS* of AI performance, a breakthrough CPU performance of over 7300 CoreMarks and advanced artificial intelligence (AI) capabilities enabling voice, vision, and real-time analytics AI applications on a single chip. The RA8P1 MCUs built on the advanced 22nm ULL process are available in single and dual-core options with a Cortex-M33 core embedded on the dual-core MCUs.
The RA8P1 MCUs integrate high-performance CPU cores with large memory, multiple external memory interfaces, and a rich peripheral set optimized for AI applications. Single and dual-core devices in 224 and 289 BGA packages are available, to address diverse use cases across broad markets. Secure Element-like functionality is built-in with advanced cryptographic security IP, immutable storage, and tamper protection, to deliver truly secure Edge AI and IoT applications.
To streamline and accelerate development, the RA8P1 MCUs are supported by the Flexible Software Package, a comprehensive set of hardware and software development tools, and RUHMI - a highly optimized AI software platform providing all necessary tools for AI development, model optimization, and conversion, fully integrated with e2 studio.
