Description
The Renesas RA8D1 MCU group features the industry’s first 32-bit graphics-enabled microcontrollers (MCUs) based on the Arm® Cortex®-M85 (CM85) core, delivering breakthrough performance of over 3000 CoreMark points at 480MHz and superior graphics capabilities that enable high resolutions display and Vision AI applications. 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 RA8D1 MCUs integrate the high-performance CM85 core with large memory, and a rich peripheral set including a high-resolution TFT-LCD controller with parallel RGB and MIPI-DSI interfaces, 2D drawing engine, 16-bit camera interface, and multiple external memory interfaces, optimized to address the needs of diverse graphics and Vision AI applications. These MCUs are available in 176 and 224-pin packages. Secure Element-like functionality is built-in with advanced cryptographic Security IP, immutable storage, a true secure boot, and tamper protection, for truly secure IoT.
The RA8D1 MCUs are fully supported by the Flexible Software Package and a comprehensive set of hardware and software development tools.
