Renesas RA6M4 MCU Group

Renesas Electronics has expanded its RA6 Series microcontrollers (MCUs) with nine RA6M4 Group MCUs. The 32-bit MCUs boost operating performance up to 200 MHz using the Arm Cortex-M33 core based on Armv8-M architecture with Arm TrustZone technology.

The MCUs are designed to deliver optimised performance together with security and connectivity supported by the easy-to-use Flexible Software Package (FSP). In addition, the Renesas partner ecosystem offers software and hardware building blocks that work out of the box with the MCUs and FSP to address Industrial 4.0, building automation, metering, healthcare and home appliance applications.

With strong security, rich connectivity, large embedded RAM with parity/ECC, low power consumption and leverage of the Arm developer and tools ecosystem, the MCUs should speed up the development of intelligent IoT edge and endpoint devices. Renesas’s Secure Crypto Engine incorporates multiple symmetric and asymmetric cryptography accelerators, advanced key management, security life cycle management, tamper detection and increased resistance to side-channel attack, in addition to Arm TrustZone technology. These integrated security features make the MCUs suitable for connected applications and enable users to realise secure element functionality in all their IoT designs.

Built on an efficient 40 nm process, the MCUs drive power consumption down to 99 uA/MHz while running the CoreMark algorithm from flash. They also support fast wake-up times of 30 µs from standby using a high-performance on-chip oscillator. Their high integration up to 1 MB code flash memory and 256 KB of SRAM (64 KB with ECC) also make the MCUs well suited for low power and safety applications. They are designed to deliver memory interface expansion, good power efficiency and several connectivity options.
