Renesas Goes After Motor Control with Machine Learning Smarts, Launches the RA8T1 Microcontroller

Renesas has introduced a brand new microcontroller line in its RA8 household, the RA8T1 — providing Arm Cortex-M85 cores with Helium on-device machine studying acceleration in a chip optimized for motor management work.”The efficiency of those MCUs is vital in high-speed electrical motor management that requires refined algorithms and software software program to run in a dependable, protected and safe method,” says Renesas Daryl Khoo, vp for embedded processing at Renesas. “The RA8T1 MCUs carry unprecedented CPU horsepower to the portfolio alongside with Helium expertise that permits our clients the extra flexibility to ship good (AI/ML) [Artificial Intelligence/Machine Learning] options with out the want for extra {hardware}.”Renesas RA8 microcontroller household grows once more, with the new RA8T1 — centered on motor management work. (📷: Renesas)The RA8T1 launches as the third string to the RA8 bow, that includes the identical Arm Cortex-M85 core, operating at 480MHz, as its predecessors — and together with Arm’s Helium extensions, which ship a claimed fourfold increase to on-device digital sign processing (DSP) and machine studying workloads over the firm’s earlier Cortex-M7 core.Unlike its siblings, nonetheless, the RA8T1 is described by Renesas as being “optimized for motor management” — due to new pulse-width modulation (PWM) timing options together with a three-phase complementary output, a double-buffer examine match register, and 5 section counting modes, plus analog peripherals together with 12-bit analog-to-digital converters (ADCs) and digital-to-analog converters (DACs) alongside high-speed comparators.Another key function for motor management work, Renesas says, is port output shutdown assist — permitting the microcontroller to mechanically shut down a motor in the occasion of an anomaly being detected. Communication buses embrace SCI, SPI, I2C/I3C, CAN/CAN-FD, Ethernet, and USB, and the elements might be specified with 1MB or 2MB of dual-bank flash reminiscence and 1MB of static-RAM, together with 512kB with Error Correction Code (ECC) assist.The firm has designed a three-phase inverter to display the new chip’s potential.
