Renesas expand low-power Arm Microcontroller offering with new RA4M2 MCU group ideal for industrial and IoT applications, evaluation kit and samples available from Anglia

Renesas RA4M2 MCU


Renesas has announced the expansion of its RA4 Series microcontrollers (MCUs) with the addition of the RA4M2 Group MCUs. These new microcontrollers 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.

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.

Key Features

  • 100MHz Arm Cortex-M33 with TrustZone
  • Secure element functionality
  • 256kB - 512kB Flash memory and 64kB SRAM with parity and 64kB SRAM with ECC
  • 8kB Data Flash to store data as in EEPROM
  • 1kB Stand-by SRAM
  • Scalable from 48-pin to 100-pin packages
  • Capacitive touch sensing unit (CTSU)
  • USB 2.0 Full Speed
  • CAN 2.0B
  • Quad SPI
  • SCI (UART, Simple SPI, Simple I2C)
  • SPI/I2C multi-master interface
  • SDHI and MMC

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 designers to realize secure element functionality, enabling safety and security in IoT edge devices for low-power applications.

Renesas EK-RA4M2

The RA4M2 Group has a dedicated evaluation kit that enables designers to effortlessly evaluate the features of the RA4M2 MCU Group and develop embedded systems applications using Renesas' Flexible Software Package (FSP) and e2 studio IDE. The easy-to-use Flexible Software Package (FSP) includes a best-in-class HAL driver and uses a GUI to simplify and dramatically accelerate the development process, while also making it easy for designers to transition from an original 8/16-bit MCU design. Designers using the RA4M2 MCUs also have access to the extensive Arm partner ecosystem, offering a wide range of tools that help speed time-to-market.
