Renesas Electronics Corporation, a leading provider of advanced semiconductor solutions, today announced the RZ/Five general purpose microprocessor units (MPUs) built around a 64-bit RISC-V processor core. The RZ/Five uses the Andes AX45MP, based on the RISC-V CPU instruction set architecture (ISA). The RZ-Five augments previously available Arm processor core-based MPUs from Renesas, expanding customer options and providing more flexibility in the product development process.
“I am delighted that Renesas is among the first to announce a general-purpose MPU built around Andes’ 64-bit RISC-V processor core,” said Hiroto Nitta, senior vice president and head of SoC business in Renesas’ IoT and Infrastructure business unit. “With the introduction of RZ/Five MPUs and ecosystem support, Renesas is taking the lead in providing market-leading RISC-V solutions.”
“RZ/Five is the first general-purpose MPU on the market to be built around an Andes 64-bit RISC-V core,” said Frankwell Lin, chairman and CEO of Andes Technology Corp. “Andes first collaborated with Renesas on the 32-bit RISC-V core and now on the 64-bit AX45MP, and I anticipate this development will lead to early adoption of customer devices in the global market built with the technology. Andes advance. RISC-V processor families.
Ideal for IoT devices
Demand is growing for IoT endpoints, such as gateways for solar inverters or home security systems, to collect sensor data and connect to servers or the cloud. In response to this need, RZ/Five is optimized to provide the performance and peripheral functions required of IoT devices. Its maximum operating frequency is 1 GHz. Peripheral features include support for multiple interfaces, such as two Gigabit Ethernet channels, two USB 2.0 channels and two CAN channels, as well as dual A/D converter modules. Support is also provided for connecting external DDR memory with error checking and correction (ECC) and failsafe functions.
Long-term Linux support via industrial-grade Linux CIP
As with the RZ/G series, a Verified Linux Package (VLP) including Civil Infrastructure Platform (CIP) Linux, an industrial-grade Linux offering long-term maintenance support for more than 10 years, is available for RZ/Five. This makes the RZ/Five series ideal for enterprise infrastructure and industrial applications that require high levels of reliability and extended life. It also allows users to significantly reduce future Linux maintenance costs.
Peripheral functions and housing compatible with the RZ/G2UL
RZ/Five’s peripheral functions and package are compatible with those of the Arm Core-based RZ/G2UL, allowing easy reuse of proven designs. The RZ/Five is also available in a smaller, more compact package to handle less complex designs more efficiently. As an evaluation environment, an RZ SMARC evaluation board kit will be offered with a SMARC 2.1 compliant module board, equivalent to the environment currently available for the RZ/G series. This kit allows switching and evaluation between an RZ/Five CPU module and an RZ/G2UL CPU module, enabling easy evaluation and shortening product development cycles.
Winning combinations with RZ/Five
Renesas will provide a complete system solution for the RZ/Five CPU module including Renesas’ DA9062 power management IC, 5P35023 programmable clock generator, AT25QL128A flash memory, and GreenPAK SLG46538 IC implementing functions devices such as system reset. These devices work together seamlessly in winning combinations, such as the SMARC system for single-core Cortex-A55 MPUs, which can be used as reference designs to reduce product development time. Renesas has developed and made available many other winning combinations that combine technically compatible devices from the Renesas product portfolio to help accelerate the design process for customers so they can get products to market faster.
