RISC-V is a free and open RISC instruction set architecture (ISA) driven by open collaboration, enabling freedom of design across many industries and applications.

Implementing commercial products including CPUs based on the RISC-V architecture enables Renesas to provide an additional degree of choice to customers and foster innovation across many industries. Renesas' adoption of RISC-V’s open source platform allows customers the flexibility and choice to work on the platform that best suits their designs. Whether it’s general purpose or application-specific processors, Renesas provides the same trusted world-class reliability, ecosystem, and support to these RISC-V portfolios of products.

Renesas leads the market introduction of RISC-V based 32-bit microcontroller products with a series of ASSPs dedicated to specific target markets, and a general purpose MCU series for the broad market. A few application areas include motor control, voice-driven human-machine interface, industrial control, mixed-signal and IoT.

The ASSP EASY group benefits from the strong cooperation with an extensive network of partners (independent design houses) to deliver the promise of a cost-effective, efficient, application-focused solutions portfolio. Those ASSPs provide a turnkey solution to Renesas' customers by specialized software, kits and tools designed and supported by the IDHs directly.

The general purpose MCUs address the global broad market with strong support from Renesas' ecosystem tools including e² studio and commercial partners. Those MCUs embed a Renesas in-house designed RISC-V CPU core, and are designed to be scalable, performant, and energy efficient.

Renesas' RZ Family of microprocessors also offers a RZ/Five microprocessor which includes a RISC-V CPU core.
