Renesas RA6M5 Microcontrollers

New 32-bit MCUs feature advanced communications and security capabilities for IoT devices

Renesas RA6M5 microcontrollers are newly-introduced products in the RA6 series which provide a wide array of security and communications functions to facilitate in-the-field software updating of IoT devices.

 

The 20 new RA6M5 Group MCUs’ communication interface options include CAN FD, an Ethernet controller with direct memory access, Full-Speed and High-Speed USB, and multiple serial interfaces.

 

The new MCUs also provide great flexibility and capacity to store and access code and data. Integrating up to 2Mbytes of Flash memory and 512kbytes of RAM, including 64kbytes with error correction code, the RA6M5 MCUs also provide an OctaSPI interface which enables designers to extend the on-chip resources with 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 32kbyte Flash blocks can be swapped to run the new code.

 

The RA6M5 MCUs employ a 200MHz Arm® Cortex®-M33 core, which offers strong security capabilities including Arm 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 new RA6M5 Group MCUs offer the same security features and software support as Renesas’ RA6M4 MCUs, which recently achieved PSA Level 2 and SESIP 1 certifications. This combination of features enables OEMs to realize secure element functionality.

 

The RA6M5 Group is supported by Renesas’ easy-to-use Flexible Software Package (FSP), which includes a best-in-class Hardware Abstraction Layer (HAL) driver. The FSP uses a GUI to simplify the development process, while also making it easy for customers to transfer functions from an original 8- or 16-bit MCU design.
