Renesas has expanded its RISC-V embedded processing portfolio with the release of an MCU optimized for advanced engine control systems.
Renesas Electronics Corp. has expanded its RISC-V embedded processing portfolio with the release of the industry’s first RISC-V MCU specifically optimized for advanced motor control systems.
The new solution allows customers to benefit from an off-the-shelf, turnkey solution for motor control applications with no development costs. Customers benefit from faster time-to-market and cost reductions by providing a pre-programmed ASSP that eliminates RISC-V related tools and software investments. Target applications for the new solution include home/building automation, healthcare appliances, home appliances, drones and more.
Renesas has taken a leadership role in providing RISC-V embedded processing solutions, having recently introduced the 64-bit general-purpose RZ/Five MPUs based on a 64-bit RISC-V CPU and the development of RISC -V automotive solutions announced. also.
How to maximize xEV engine performance
Renesas Electronics Corp.’s Nachiket Hardas, Senior Principal Manager of Automotive New Business Creation Division and Automotive Solution Business Unit, will speak at the upcoming Electronics Asia Conference (EAC) 2022 on the company’s xEV inverter reference, a comprehensive solution, It will help you reduce overall development costs, reduce time to market and realize your own cost-effective inverter solution.

“As a leader in embedded processing, Renesas delivers the solutions our customers demand on any number of platforms,” said Roger Wendelken, senior vice president in Renesas’ IoT and infrastructure business unit. “This RISC-V based ASSP offers an optimal combination of low cost, fast time to market and excellent performance. It is a great addition to our current portfolio and is reaching new customers and emerging markets around the world.”
Renesas’ new ASSP R9A02G020 motor controller is based on Andes Technology Corp’s RISC-V processing IP. Franklin Lin, CEO of Andes, said, “We are excited that Andes’ entry-level RISC-V processor IP is bringing processing power to Renesas’ R9A02G020 MCU ASSP. We believe that Renesas bringing a high-performance, low-power MCU ASSP to the market will accelerate the integration of RISC-V in a wide range of applications. It will also encourage software developers to develop more creative and efficient applications for RISC-V, accelerating the adoption of this next-generation paradigm.”
Renesas will supply the new RISC-V ASSP pre-programmed with custom application code developed by leading independent design houses (IDHs) BFG Engineering and DigiPower (HK) Technology Ltd. was developed. Both BFG and DigiPower have specialized motor control expertise and proven customer support capabilities. BFG is known for sensorless algorithms that enable customers to reduce engine start times. DigiPower has been developing cost-optimized, scalable motor drive solutions since 2008 and has engineered dedicated solutions to control refrigerator compressors, fans, pumps and more. Both BFG and DigiPower will work with customers to finalize designs and support the transition to production.
SEGGER Microcontroller GmbH has also joined this project. The full SEGGER ecosystem, including Embedded Studio and J-Link, was a key element used to create and test these motor control solutions.
Key features of the R9A02G020 motor control ASSP solution include: innovative cost-optimized 32MHz 32-bit CPU core based on license-free RISC-V ISA; extensive analog IP functionality; advanced motor control timers and two watchdog timers; small 24- and 32-pin QFN packages; High temperature support up to 125°C for harsh operating environments; and sensorless vector control for a BLDC motor, 1/3 shunt, PFC and Hall sensor inputs.
