The announcement makes Renesas among the first in the industry to independently develop a CPU core for the 32-bit general-purpose RISC-V market, providing an open and flexible platform for IoT, consumer electronics, healthcare and industrial systems.
The RISC-V CPU core will complement Renesas’ existing IP portfolio of 32-bit microcontrollers (MCUs), including the proprietary RX Family and the RA Family based on the Arm Cortex-M architecture.
RISC-V is an open ISA which has been gaining popularity in the semiconductor industry, due to its flexibility, scalability, power efficiency and open ecosystem. While many MCU providers have recently created joint investment alliances to accelerate their development of RISC-V products, Renesas has already developed a new RISC-V core on its own.
This versatile CPU can serve as a main application controller, a complementary secondary core in SoCs, on-chip subsystems, or even in deeply embedded ASSPs and is seen as helping to position Renesas as a leader in the emerging RISC-V market, following previous introductions of its 32-bit voice-control and motor-control ASSP devices, as well as the RZ/Five 64-bit general purpose microprocessors (MPUs), which were built on CPU cores developed by Andes Technology Corp.
Commenting Daryl Khoo, Vice President of the IoT Platform Division at Renesas said, “This new core extends our leadership in the RISC-V market and uniquely positions us to deliver more solutions that accommodate a diverse range of requirements.”
“This achievement exemplifies how RISC-V ecosystem partners, such as Renesas, are rapidly advancing RISC-V innovation. Our RISC-V community now spans 70 countries with more than 4,000 members, and we eagerly anticipate further innovations emerging from this dynamic, expanding market,” added Calista Redmond, CEO at RISC-V International.
The Renesas RISC-V CPU achieves a 3.27 CoreMark/MHz performance and includes extensions to improve performance, while reducing code size.
Renesas is sampling devices based on the new core with select customers and said that it plans to launch its first RISC-V-based MCU and associated development tools in Q1 2024.
