Renesas Introduces RA6T2 MCUs for Next-Generation Motor Control in Inverter Appliances, Building Automation and Industrial Drives

New MCUs Achieve Higher-Performance, Cost-Efficient Motor Control with a High Frequency Arm Cortex®-M33 Core, a Hardware Accelerator and a Targeted Feature Set; New, Easy-to-Use Motor Control Tools and Kits Speed Design Process

TOKYO, Japan, December 8, 2021 ― Renesas Electronics Corporation (TSE:6723), a premier supplier of advanced semiconductor solutions, today introduced the RA6T2 Group MCUs featuring a rich set of peripheral functions and hardware accelerator designed specifically for motor control. The new RA6T2 Group MCUs deliver an unmatched combination of performance, features, and cost-efficiency for motor control designs in home appliances, smart home, industrial and building automation, as well as inverter control.

Based on the 240-MHz Arm Cortex®-M33 core, the new RA6T2 32-bit MCUs feature peripherals optimized for high performance and precision motor control in order to reduce bill of materials (BOM) cost while boosting performance. For example, two independent ADC units offer high-speed conversion with a maximum speed of 0.16 µsec and include a simultaneous sample and hold function for three channels to detect the three-phase current of a motor. In addition, amplifiers that can set the gain according to the input voltage range are built in, and analog components that were previously external are incorporated, including comparators which detect abnormal voltage input and over current. In addition, the adjustable PWM timer makes it easy to port existing algorithms. It also provides, in cooperation with other analog functions, a PWM output cutoff safety function in the event of an abnormality. With these features, a single RA6T2 MCU can simultaneously control up to two brushless DC (BLDC) motors.

The embedded hardware accelerator includes both a Trigonometric Function Unit (TFU) and an Infinite Impulse Response (IIR) filter. The TFU performs high speed calculations without the need for lookup tables, enabling effective use of ROM. The IIR filter offers coefficient setting methods that ease porting from existing algorithms.

“Our motor control customers are looking to differentiate their products in very competitive markets,” said Roger Wendelken, Senior Vice President in the IoT and Infrastructure Business Unit at Renesas. “The RA6T2 Group delivers a unique combination of performance and features that enable cost-effective, powerful designs for a wide variety of applications.”

  • Safety features include a PWM output monitor that shuts off the PWM output when an abnormality is detected; Memory Protection Unit; ECC in SRAM, ADC self-test

Winning Combinations

Renesas has combined the RA6T2 with complementary components that work together seamlessly to create Winning Combinations for motor control. An example of one of these Winning Combinations is the BLDC Traction Motor Control design that also includes Renesas’ new RAA227063 Smart Gate Driver optimized for motor control. Renesas offers more than 250 Winning Combinations with compatible devices for a wide range of applications and end products. They can be found at


20 new RA6T2 MCUs are available today in five package options. Renesas is also offering a wide range of design tools, including the RTK0EMA270S00020BJ Motor Control Kit, a CPU board, an Inverter Board, and a Motor Work Bench GUI tool with real-time debugging and digital oscilloscope functionality.
