RA4M2 Microcontrollers for Low Power Consumption, High Performance and Enhanced Security in Industrial and IoT Applications

RA4M2 Group Microcontrollers from Renesas Electronics

Renesas Electronics Corporation has expanded its RA4 series Microcontrollers (MCUs) with 12 new RA4M2 Group MCUs. Designed with Arm Cortex –M33 core and Armv8-M architecture, the highly power-efficient microcontrollers offer an operating current of only 80µA/MHz in active mode, and a low standby current of 0.7mA. The RA4M2 Group can operate at frequencies up to 100MHz and deliver extremely fast wake-up time from standby of 30µs; hence they are ideal for performance-hungry, low power applications such as industrial and IoT edge devices.


The RA4M2 Group of microcontrollers feature the Arm TrustZone technology and Renesas’ Secure Crypto Engine that incorporates multiple symmetric and asymmetric cryptography accelerators, advanced key management, security lifecycle management, power analysis resistance, and tamper detection. The new devices deliver an exceptional combination of very low power consumption, high performance, and enhanced security features that positions them as ideal solutions for industrial and IoT applications.


With the help of the easy to use Flexible Software Package(FSP), users can accelerate the development process; they can also access the extensive Arm partner ecosystem, offering a wide range of tools that help speed time-to-market. The RA4M2 MCUs are available now from Renesas’ worldwide distributors
