Description
The Renesas RA8D2 group comprises 32-bit single and dual-core graphics-enabled MCUs with 1GHz Arm® Cortex®-M85 with Helium™ Vector Extensions and 250MHz Cortex-M33 cores. These MCUs deliver ultra-high performance of over 7300 CoreMark and superior graphics capabilities that enable high-resolution TFT-LCD displays up to WXGA, and vision AI applications.
Integrating the high-performance cores with large on-chip memory, multiple high-throughput memory interfaces, and a rich set of graphics peripherals – a high-resolution LCD controller with parallel RGB and MIPI DSI interfaces, 2D drawing engine, 16-bit parallel CEU, and MIPI CSI-2 camera interfaces – the RA8D2 MCUs address the needs of demanding graphics/HMI and AI applications. Built on the advanced 22nm ULL TSMC process, these devices offer significantly lower active currents and have several low-power features developed to reduce the overall power consumption, while still providing high performance. The RA8D2 MCUs are available in 224, 289, and 303 BGA packages. Secure Element-like functionality is built-in with new cryptographic security IP, secure boot, immutable storage, and tamper protection, enabling truly secure consumer/IoT applications.
The RA8D2 MCUs are fully supported by the Flexible Software Package and a comprehensive set of hardware and software development tools.
