Description

The Renesas RA8E2 MCU group features entry-line graphics-enabled 32-bit microcontrollers (MCUs) based on the Arm® Cortex®-M85 (CM85) core with Helium and TrustZone®, delivering breakthrough performance of over 3000 CoreMark points at 480 MHz, and graphics capabilities that drive TFT-LCD displays. These MCUs address diverse high-performance graphics applications in industrial automation, home appliances, smart home, consumer, building/home automation, and medical/healthcare market segments.

The RA8E2 MCUs integrate the high-performance CM85 core with large memory, and an optimized peripheral set including a graphics TFT-LCD controller with parallel RGB interface, 2D drawing engine, and multiple external memory interfaces, which addresses the needs of price-sensitive graphics applications. These MCUs are available in 224-pin packages.

The RA8E2 MCUs are fully supported by the RA Flexible Software Package and a comprehensive set of hardware and software development tools.
