Renesas RA4M2 Group Microcontrollers

With the introduction of 12 new RA4M2 Group microcontrollers, Renesas Electronics Corporation has expanded the low power industrial and IoT-edge applications reach. Combining high performance and security features with low power consumption, these highly power-efficient devices employ the Arm Cortex-M33 core based on Armv8-M architecture and feature Arm TrustZone technology and Renesas’ Secure Crypto Engine.

The new RA4M2 Group Microcontrollers have operating frequencies of up to 100 MHz, 80 µA/MHz operating current in active mode, and a low standby current of 0.7 mA. Additionally, these have an extremely fast wake-up time from standby of 30 µs. The MCUs are supported by the easy-to-use Flexible Software Package (FSP) that comes with the best-in-class HAL driver. The FSP uses a GUI to simplify and dramatically accelerate the development process, while also making it easy for customers to transition from an original 8/16-bit MCU design.

Key Features of the RA4M2 Group MCUs

  • Very Low power consumption of 80 μA/MHz in active mode; 30 µs wakeup time
  • 100-MHz Arm Cortex-M33 with TrustZone technology
  • Renesas’ Secure Crypto Engine as part of a full security solution
  • Scalable from 48- to 100-pin LQFP packages; also available in 48-pin QFNs
  • Integrated flash memory of 512KB, 384KB, or 256KB; 128K SRAM
  • Capacitive touch sensing unit
  • USB 2.0 Full Speed
  • Advanced analog with one ADC (Analog-to-Digital Converter) unit
  • QuadSPI

With these MCUs, designers also get access to 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.
