Renesas expands low-power industrial and IoT applications reach with RA4M2 MCU group

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

The new devices are said to deliver an exceptional combination of low power consumption, high performance, and enhanced security features that positions them as ideal solutions for industrial and IoT applications.

The power-efficient RA4M2 Group offer an operating current of 80 µA/MHz in active mode, and low standby current of 0.7 mA. Even with these specifications, the new devices reportedly have a fast wake-up 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 realise secure element functionality, enabling safety and security in IoT edge devices for low-power applications.

“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,” says Roger Wendelken, SVP in Renesas’ IoT and Infrastructure Business Unit. “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.”

 Key features of the RA4M2 group include:

  • 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
  • SDHI

The RA4M2 Group is supported by the Flexible Software Package (FSP), which includes an HAL driver. The FSP uses a GUI (graphical user interface) 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. 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.

The RA4M2 MCUs can be combined with Renesas’ complementary analogue and power offerings to create solutions for a variety of applications. These showcase the capabilities of the RA4M2 MCUs and the breadth and depth of Renesas’ product line-up.
