Renesas RA4M2 Group MCUs

Renesas Electronics has added 12 more microcontrollers (MCUs) to its RA4 Group, delivering a combination of low power consumption, high performance and enhanced security features.

The power-efficient MCUs offer an operating current of 80 µA/MHz in active mode, and low standby current of 0.7 mA. The devices also have a fast wake-up time from standby of 30 µs. With operating frequencies up to 100 MHz, they are suitable for performance-hungry, low-power applications such as industrial and IoT edge devices.

The MCUs employ the Arm Cortex-M33 core based on Armv8-M architecture. They feature Arm TrustZone technology and Renesas’s Secure Crypto Engine. The Secure Crypto Engine incorporates multiple symmetric and asymmetric cryptography accelerators, advanced key management, security life cycle management, power analysis resistance and tamper detection. This combination enables users to realise secure element functionality, enabling safety and security in IoT edge devices for low-power applications.

The group is supported by the easy-to-use Flexible Software Package (FSP), which includes a HAL driver. The FSP uses a GUI to simplify and accelerate the development process, while also making it easy for customers to transition from an original 8-/16-bit MCU design.

The MCUs can be combined with Renesas’s complementary analog and power offerings to create comprehensive solutions for a variety of applications. Designers using the MCUs also have access to the extensive Arm partner ecosystem, offering a wide range of tools that help reduce time to market.
