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 MPUs or application-specific MCUs, 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. 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 to deliver the promise of a cost-effective, efficient, application-focused solutions portfolio.
Renesas' RZ Family of microprocessors also offers a RZ/Five microprocessor which includes a RISC-V CPU core.
