Renesas RA4M2 Microcontrollers (MCUs)
Based on Arm Cortex-M33 core and offering advanced security features for industrial and IoT applications
Renesas has introduced the RA4M2 Microcontroller (MCU) family, adding 12 new products in the Renesas RA Family of microcontrollers. They offer a combination of very low power consumption, high performance, and enhanced security capabilities. The new RA4M2 MCUs’ features make them ideal solutions for industrial systems and IoT edge devices.
The highly power-efficient RA4M2 Group MCUs draw an operating current of only 80µA/MHz in active mode, and a low stand-by current of 0.7mA. Low-power operation does not prevent these new devices from providing a fast response: wake-up time from stand-by is just 30µs, and maximum operating frequency is 100MHz.
The RA4M2 MCUs take advantage of the specialist security capabilities of the Arm® Cortex®-M33 core, including the TrustZone® technology for secure partitioning of operations involving trusted hardware peripherals. This technology is augmented in the RA4M2 MCUs by Renesas’ Secure Crypto Engine, which incorporates multiple symmetric and asymmetric cryptography accelerators, advanced key management, security lifecycle management, resistance to power analysis, and tamper detection.
This rich suite of advanced security features enables customers to realize the functionality of a secure element, providing an integrated solution for the requirements of IoT edge devices.
The RA4M2 Group is supported by the easy-to-use Flexible Software Package (FSP), which includes a best-in-class driver for hardware abstraction layers. The FSP uses a GUI to simplify and accelerate the development process, while also making it easy for customers to make the transition from an 8- or 16-bit MCU design.
Demonstration applications such as a smart IoT air purifier and an industrial CAN sensor network can be found here.
