Renesas Introduces New RA4M2 MCU Group in Arm Cortex-Based MCU Family

Advanced semiconductor solutions supplier Renesas Electronics Corporation has expanded its RA4 Series microcontrollers (MCUs) with 12 new RA4M2 Group MCUs.

These 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.

Commenting on the development, Roger Wendelken, Senior Vice President in Renesas’ IoT and Infrastructure Business Unit said “the RA4M2 MCU Group is the ideal solution for very low power IoT edge applications, combining high performance and security features with low power consumption.”

Wendelken added “our rollout of market-leading solutions within the RA Family is a testament to the design, manufacturing and marketing prowess that has made Renesas the pre-eminent MCU supplier worldwide.”

The company said that the highly power-efficient RA4M2 Group offer a market-leading operating current of only 80 µA/MHz in active mode, and low standby current of 0.7 mA. Even with these leading specifications, the new devices have an extremely fast wakeup time from standby of 30 µs. With operating frequencies up to 100 MHz, the RA4M2 MCUs are ideal for performance hungry, low power applications such as industrial and IoT edge devices.

The RA4M2 MCUs employ the Arm® Cortex®-M33 core based on Armv8-M architecture. They feature 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. This combination enables customers to realize secure element functionality, enabling safety and security in IoT edge devices for low-power applications.

Also, the RA4M2 MCUs can be combined with Renesas’ complementary analog and power offerings to create comprehensive solutions for a variety of applications. These “Winning Combinations” showcase the unique capabilities of the RA4M2 MCUs and the breadth and depth of Renesas’ product line-up. The RA4M2 MCUs are available now from Renesas’ worldwide distributors.
