Renesas RA6M5 Group of Microcontrollers

New MCUs deliver extensive communications options, flexible memory and strong security

The Renesas RA6M5 series of Microcontrollers (MCUs), has expanded their popular RA6 Series with an extensive new lineup that completes the mainstream of RA6 Series MCUs.

The new microcontrollers offer a very wide array of communications options, generous on-chip memory, and Renesas’ best-in-class security features, enabling you to create new and innovative IoT designs.

The new RA6M5 MCUs offer numerous communication interface options, including CAN FD, Ethernet MAC with DMA, USB Full Speed and High Speed, and multiple serial interfaces.

Renesas RA6M5 microcontrollers support a wide range of applications thanks to up to 2MB on-chip flash and 512KB on-chip RAM. An OctaSPI interface enables designers to extend the on-chip flash and RAM even more. Error correction code (ECC) is also supported in the RA6M5 RAM.


Renesas — RA6M5 creative


Arm® Cortex®-M33 Core

The RA6M5 MCUs employ the iconic Arm® Cortex®-M33 core based on Armv8-M architecture, 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.

Memory Block Feature

In addition to the RA family’s built-in security features, the RA6M5 MCU features memory block swap functionality for applications in which in-field firmware updates are required.


RA6M5 MCUs feature PSA Certified Level 2 and SESIP1 certification, which allows you to execute secure element functionality, unmatched safety and security for highly connected IoT devices.

Experience unmatched flexibility and performance with the RA6M5 Microcontroller Group by Renesas.
