The Renesas Advanced (RA) Family of 32-bit Arm Cortex-M microcontrollers (MCUs) aims to deliver the ultimate combination of optimized performance, security, connectivity, peripheral IP, and easy-to-use Flexible Software Package (FSP) for next generation embedded solutions.

To support the new family, Renesas Electronics has built a comprehensive partner ecosystem to deliver an array of software and hardware building blocks that will work out of the box with RA MCUs. The RA Family ecosystem will help accelerate the development of IoT applications with core technologies such as security, safety, connectivity and HMI. The RA Family is PSA Certified Level 1 and includes the RA2 Series (up to 60 MHz), RA4 Series (up to 100 MHz), RA6 Series (up to 200 MHz), and the dual-core RA8 Series, to be released later.

“RA MCUs offer customers the ultimate IoT security by combining our Secure Crypto Engine IP with NIST CAVP certifications on top of Arm TrustZone for Armv8-M, while also providing tamper detection and reinforcing resistance to side-channel attacks,” explains Roger Wendelken, Senior Vice President of Renesas’ IoT and Infrastructure Business Unit.

“Scalability and compatibility across the RA Family lets customers build a range of products, and they can quickly begin development with our flexible software package using Amazon FreeRTOS, ThreadX, or other RTOS and middleware solutions.”

The first five RA MCU Groups available today are comprised of 32 scalable MCUs with Arm Cortex-M4 and Cortex-M23 processor cores. They feature pin counts of 32-pins to 176-pins, along with 256 KB to 2 MB of code flash memory, 32 KB to 640 KB SRAM, and connectivity such as USB, CAN and Ethernet. It is easy to transition within the RA Family thanks to feature and pin compatibility. Each RA MCU Group provides superior active and standby power, and enhanced features such as Renesas’ popular HMI capacitive touch technology.
