RA Family Arm® Cortex® Microcontrollers

Renesas Electronics RA Family Arm® Cortex® Microcontrollers are 32-bit MCUs based on the Arm Cortex-M core architecture, with a wide range of integrated system peripheral IPs, making them ideal for next-generation embedded solutions. Each group of RA Series MCUs offers unique features such as the capacitive touch sensing unit (CTSU),  Secure Crypto Engine (SCE) supporting sync/async crypto acceleration, 24-bit analogue-to-digital converter (ADC), and segment or TFT LCD controllers. The Renesas RA MCUs make it easy to develop IoT edge devices with embedded artificial intelligence (e-AI), using flexible software development tools from Renesas and the Arm partner ecosystem. The RA Series encompasses a broad range of compatible products that provide seamless scalability from small-scale to large-scale applications.
