Renesas Electronics has added 20 new RA6M5 microcontrollers to its main line of RA6 series Arm Cortex M33-Based MCUs. These new devices offer a wide array of communications options, generous on-chip memory, and enhanced security features enabling customers to create new and innovative IoT designs.

The numerous communication interface options that these MCUs offers include CAN FD, Ethernet MAC with DMA, USB Full Speed, and High Speed, and multiple serial interfaces. The new MCUs integrate up to 2MB on-chip flash and 512KB on-chip RAM that helps support a wide range of applications. They provide an OctaSPI interface that enables designers to extend the on-chip flash and RAM even more.

Additionally, the RA6M5 Group MCUs support error correction code (ECC) in the RAM. Besides, there is a memory block swap feature in conjunction with the intrinsic security built into RA Family devices. A selectable amount of 32kB flash blocks can be swapped to the new firmware after the new firmware is written to the flash using background operation (BGO). The new RA6M5 Group of microcontrollers employs the Arm Cortex-M33 core based on Armv8-M architecture and features Arm TrustZone technology and Renesas’ Secure Crypto Engine.

Roger Wendelken, Senior Vice President in Renesas’ IoT and Infrastructure Business Unit said, The RA6M5 MCU Group offers our customers seemingly ‘endless’ communications options, enabling the flexibility to share data in a wide variety of different ways to address numerous IoT applications. This functionality, combined with ample on-chip memory and our industry-leading security features make these devices true powerhouses for implementing IoT designs.”

The RA6M5 Group is supported by the easy-to-use Flexible Software Package (FSP), which includes a best-in-class HAL driver. The FSP uses a GUI to simplify and dramatically accelerate the development process, while also making it easy for customers to transition from an original 8/16-bit MCU design. The RA6M5 MCUs and the EK-RA6M5 Evaluation Kit (p/n RTK7EKA6M5S00001BE) are available from Renesas and its worldwide distributors.
