The new 32-bit MCUs also feature a boost to performance that sees them operate at up to 200 MHz using Arm’s Cortex-M33 core. The core is based on the Armv8-M architecture with Arm TrustZone technology. The RA6M4 MCUs provide high performance combined with leading-edge security and connectivity supported by the Flexible Software Package (FSP). Additionally, the Renesas partner ecosystem helps designs get up and running with software and hardware building blocks that work straight from the box with RA6M4 MCUs and FSP to address dedicated applications.
The MCUs are also able to offer large embedded RAM with parity/ECC, low power consumption, and use of the Arm developer and tools ecosystem. Renesas’ enhanced Secure Crypto Engine delivers excellent security solutions. The engine integrates multiple symmetric and asymmetric cryptography accelerators, advanced key management, security lifecycle management, tamper detection, and increased resistance to side-channel attack, in addition to Arm TrustZone technology.
“Delivering on our promise at the launch of the RA MCU Family last October, I’m proud to announce its expansion with the RA6M4 MCUs. They offer customers best-in-class performance and security enhancements built with Arm Cortex-M33 cores that clearly deliver more memory, memory interface expansion, better power efficiency and wake-up time, and more connectivity options,” said Roger Wendelken, Senior Vice President of Renesas’ IoT and Infrastructure Business Unit. “We intend to delight our customers who appreciate the higher level of security and IoT connectivity that the RA6M4 MCU Group brings with the confidence and ease of use that only comes by designing with Arm and securing with Arm TrustZone technology.”
“IoT edge and endpoint technologies are opening up new opportunities for developers to build smaller devices, with greater privacy and less dependence on the cloud,” said Dipti Vachani, senior vice president and general manager, Automotive and IoT Line of Business at Arm. “The RA6M4 MCUs move intelligence closer to the data, with Arm TrustZone technology built in to ensure privacy and data integrity, helping securely accelerate the growth of IoT.”
The MCUs are built on a highly efficient 40nm process which can drive consumption down to 99uA/MHz while running the CoreMark algorithm from flash. They also support fast wakeup times of 30 µs from standby using a high-performance on-chip oscillator. Their high integration up to 1MB code flash memory and 256 KB of SRAM (64 KB with ECC) also make the RA6M4 MCUs well suited for low power and safety applications.
