New RA6M5 Group of MCUs with Extensive Communication, Flexible Memory, and Enhanced Security Features for IoT Applications

RA6M5 Group of MCUs

Renesas Electronics Corporation has expanded its RA6 Series microcontrollers (MCUs) with 20 new RA6M5 Group MCUs that offer a very wide array of communications options, generous on-chip memory, and Renesas’ best-in-class security features. The new devices deliver unmatched flexibility in sharing critical data in IoT Systems. The MCUs come with numerous interface options such as CAN FD, Ethernet MAC with DMA, USB Full Speed, and High Speed, and multiple serial interfaces.


The new RA6M5 Group of MCUs has up to 2MB on-chip flash and 512KB on-chip RAM and provides an OctaSPI interface that enables designers to extend the on-chip flash and RAM even more. After new firmware is written to the flash using background operation (BGO), a selectable amount of 32kB flash blocks can be swapped to the new firmware.


The RA6M5 MCUs come with an Arm Cortex-M33 core based on Armv8-M architecture and features Arm TrustZone technology and Renesas’ Secure Crypto Engine. The Secure Crypto Engine incorporates multiple symmetric and asymmetric cryptography accelerators, advanced key management, security lifecycle management, power analysis resistance, and tamper detection.  All these features allow the customers to realize secure element functionality for providing unmatched safety and security for highly connected IoT devices.
