RA6M4 Block Diagram
Description
The Renesas RA6M4 group of microcontrollers (MCUs) uses the high-performance Arm® Cortex®-M33 core with TrustZone®. In concert with the Secure Crypto Engine it offers Secure Element functionality. The integrated Ethernet MAC with individual DMA ensures high data throughput. The RA6M4 is built on a highly efficient 40nm process and is supported by an open and flexible ecosystem concept—the Flexible Software Package (FSP), built on FreeRTOS—and is expandable to use other RTOSes and middleware. The RA6M4 is suitable for IoT applications requiring Ethernet, future proof security, large embedded RAM, and low active power consumption down to 99µA/MHz running the CoreMark® algorithm from Flash.

Device Lifecycle Management (DLM) is the management of the process by which a product goes from inception to development to production and then eventually end-of-life.
- Sample CodeLearn how Renesas MCU security revolves around integrated security engines. There are different types of security engines across the RA MCU. Users can find the specific engine used in a particular MCU from its hardware user’s manual. The security engines can operate in two different modes, called Compatibility Mode and Protected Mode. The application note “Renesas Security Engine Operational Modes” explains the definition of the two modes and their use cases.
- Sample CodeUse the following sample program to operate on the RA evaluation board. This sample program package supports the Ethernet-based Modbus TCP protocol.
