Description

The RA8E1 MCU Group features entry-line 32-bit microcontrollers (MCU) based on the Arm® Cortex®-M85 (CM85) core with Helium and TrustZone®, delivering breakthrough performance of 6.39 CoreMarks/MHz, with fully deterministic, low-latency, real-time operation that enables customers’ most demanding application needs. These are general-purpose MCUs 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 RA8E1 MCUs integrate the high-performance CM85 core with memory, multiple external interfaces and an optimized peripheral set that addresses the needs of price-sensitive applications. RA8E1 MCUs are available in 100 and 144-pin LQFP packages, to serve the needs of a broad range of high-performance applications. 

The RA8E1 MCUs are fully supported by the RA Flexible Software Package and a comprehensive set of hardware and software development tools.
