Renesas Unveils Motor Control MCUs with Fast Networking

Renesas Electronics Corporation, a premier supplier of advanced semiconductor solutions, today introduced the RA8T2 microcontroller (MCU) group for high-end motor control. Based on a 1 GHz Arm® Cortex®-M85 processor with an optional 250 MHz Arm® Cortex®-M33 processor, the RA8T2 devices deliver an unmatched level of performance to address real-time control of high-end motors in industrial equipment, robots, and other systems where high-speed precision operation is required. The optional Cortex-M33 processor enables customers to combine real-time control with communication functions and non-real-time operations on a single chip, saving cost, power and board space.

The RA8T2 MCUs take advantage of the high performance of the Arm Cortex-M85 processor and Arm’s Helium™ technology to offer a significant performance boost for digital signal processor (DSP) and machine learning (ML) implementations. This added performance enables AI functions that can predict maintenance requirements for motors, reducing costly downtime.

In addition to their exceptional processing power, the RA8T2 MCUs provide high-speed networking support through multiple communications interfaces, including two Gigabit Ethernet MACs with DMA, a two-port EtherCAT slave, and many others. High-speed communication is critical in factory automation, where each device is linked to a network within the factory, and is constantly synchronized with other machines to send and receive commands and data.

RA8T2 devices are equipped with up to 1MB of high-speed MRAM (Magnetoresistive Random Access Memory) non-volatile memory with 100 MHz access. MRAM offers faster write speeds along with higher endurance and retention compared with Flash. In addition, RA8T2 is equipped with a TCM (Tightly Coupled Memory) with 256KB for Cortex-M85 and 128KB for Cortex-M33. TCM provides users with high-precision real-time performance with less jitter and can provide stable performance in motor control processing with many interrupts and branches.

“The RA8T2 Group extends our long-term industry leadership in motor control solutions, offering unparalleled levels of performance and functionality,” said Daryl Khoo, Vice President of the Embedded Processing Marketing Division at ルネサス. “These devices showcase the breadth and depth of our technology and demonstrate our deep understanding of what our motor control customers need to build next-generation factory automation and robotics products.”
