This product within the RISC-V based ASSP EASY group, targets motor control applications. The hardware specification is designed for efficient handling of brushless-DC motors in one or three shunt configurations, both in sensor-less mode or with external sensor inputs.

The application software implementing the motor control functionality is pre-developed and programmed within the device at factory production, with specialized application code developed by IDHs (independent design houses). This enables users to add a sophisticated field-oriented motor control functionality without any effort in terms of development, testing and validation of the implementation. An external host can control the ASSP via a simple serial interface, offloading the motor control functionality in the system, while handling the application-level tasks.

The end-product is composed of a combination of Renesas hardware and third-party software. The IDHs are partners with demonstrated specialized expertise in the motor control field and proven customer support capability, to bring the projects to completion and secure the successful transition to mass-production. The strongly collaborative solution with the IDH is a fundamental value proposition and the key to success.

The R9A02G020 RISC-V MCU ASSP hardware is specifically optimized for advanced motor control systems. Alongside ecosystem partners, this provides a complete, production-ready motor control system solution. With 32MHz performance, 48/16KB of Flash/RAM memory, advanced analog features, the R9A02G020 provides the foundation for a turnkey motor control solution. The availability of small package options and highest temperature support make such ASSP ideal for highly space-constrained PCB designs, within harsh environmental conditions.
