Renesas extends RISC-V embedded processing portfolio with new motor control ASSP solution

Düsseldorf, Germany – Renesas Electronics Corporation, a supplier of advanced semiconductor solutions, introduced the RISC-V MCU specifically optimised for advanced motor control systems. The new solution enables customers to benefit from a ready-to-use, turnkey solution for motor control applications, with no development cost. Customers benefit from reduced time to market and cost reductions with the delivery of a pre-programmed ASSP that eliminates RISC-V related tools and software investment. Target applications for the new solution include home/building automation, healthcare devices, home appliances, drones and more.

Renesas has taken a leadership role in delivering 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 announcing development of RISC-V automotive solutions, as well.

“As the leading embedded processing provider, Renesas delivers the solutions our customers demand across any number of platforms” says Roger Wendelken, senior vice president in Renesas’ IoT and infrastructure business unit. “This RISC-V-based ASSP offers an optimum combination of low cost, quick time-to-market, and outstanding performance. It complements our current portfolio nicely, reaching out to new customers and emerging markets across the globe.”

Optimised solution in collaboration with global partners

Renesas’ new R9A02G020 motor control ASSP is based on RISC-V processing IP from Andes Technology Corp. Franklin Lin, CEO of Andes, says “We are thrilled to have Andes’ entry-level RISC-V processor IP providing computing power in Renesas’ R9A02G020 MCU ASSP. We believe Renesas making a powerful, low-power MCU ASSP available to the market will accelerate the incorporation of RISC-V in a broad array of applications. It will also encourage software developers to produce more creative and efficient applications for RISC-V, thus speeding up adoption of this next generation paradigm.”

Renesas will deliver the new RISC-V ASSP pre-programmed with specialised application code developed by Independent Design Houses (IDHs) BFG Engineering and DigiPower (HK) Technology Ltd. Both BFG and DigiPower have specialised expertise in the motor control field and proven customer support capability. BFG is famous for sensor-less algorithms that allow customers to reduce motor start-up times. DigiPower has been creating cost-optimised, scalable motor drive solutions since 2008 and has designed specific solutions for control of refrigerator compressors, fans, pumps and more. Both BFG and DigiPower will work with customers to finalise designs and aid the transition to production.

SEGGER Microcontroller GmbH has also partnered in this effort. The complete SEGGER ecosystem, including Embedded Studio and J-Link, was a key element used to create and test these motor control solutions.
