The Renesas RA6 series of microcontrollers provides a wide array of security and communications functions alongside high processor performance, to give the combination of features required in the next generation of IoT devices.
The RA6M5 MCU communication interface options include CAN FD, an Ethernet controller with direct memory access, Full-Speed and High-Speed USB, and multiple serial interfaces.
The MCUs also provide great flexibility and capacity to store and access code and data. Integrating up to 2 Mbytes of Flash memory and 512 kbytes of RAM, including 64 kbytes with error correction code, the RA6M5 MCUs also provide an OctaSPI interface which enables designers to extend the on-chip resources with fast access to external memory.
The memory block-swap feature and strong intrinsic security make the RA6M5 Group MCUs the best choice for applications in which in-the-field firmware updates are required. After new firmware is written to Flash in the background, a selectable number of 32 kbyte Flash blocks can be swapped to run the new code.
The RA6M5 MCUs employ a 200 MHz Arm® Cortex®-M33 core, which offers strong security capabilities including TrustZone® technology. The MCUs’ Renesas secure crypto engine incorporates multiple symmetric and asymmetric cryptography accelerators, advanced key management, security lifecycle management, resistance to power analysis, and tamper detection. The RA6M5 MCUs offer the same security features and software support as the Renesas RA6M4 MCUs, including PSA Level 2 and SESIP Level 1 certification. This combination of features enables OEMs to realize secure element functionality.
The RA6M5 series is supported by an easy-to-use flexible software package (FSP), which includes a best-in-class hardware abstraction layer driver. The FSP uses a GUI to simplify the development process, while also making it easy for developers to transfer functions from an original 8- or 16-bit MCU design.
Kit part number: EK-RA6M5
The EK-RA6M5 evaluation kit enables developers to evaluate the features of the RA6M5 MCU series and develop embedded systems using the FSP and e2 studio integrated development environment.
