Renesas Electronics (TSE: 6723), a global semiconductor solutions provider, recently announced the launch of a new general-purpose 32-bit RISC-V microcontroller (MCU) - R9A02G021. This product is the industry's first based on an internally developed CPU core. RISC-V MCU. Although many MCU suppliers have recently joined investment alliances to promote RISC-V product development, Renesas Electronics has taken the lead in independently designing and testing this new RISC-V core, and the core has been successfully used in commercial products and has begun Sold worldwide. The R9A02G021 MCU product family provides a clear development path for embedded system designers to develop a variety of power-sensitive and cost-sensitive applications based on the open source instruction set architecture (ISA).
Although RISC-V solutions currently on the market are mainly targeted at specific application areas, the R9A02G021 MCU product series is designed for multiple end markets, including the Internet of Things, consumer electronics, medical equipment, small appliances, and industrial systems. Similar to existing general-purpose MCUs, designers can take advantage of a comprehensive development environment built by Renesas and its extensive network of tool chain partners to significantly reduce costs, save engineering resources, and shorten development cycles.
"From our RISC-V-specific ASSP to this new general-purpose MCU, our goal is to provide customers with commercially viable products that enable them to quickly go to market," said Daryl Khoo, vice president of the Embedded Processing First Business Unit at Renesas Electronics. volume production, while demonstrating the advantages of the RISC-V architecture. In addition, customers often face many complex design challenges and choices, such as performance, power consumption, memory or CPU architecture trade-offs. The new RISC-V MCU is for those who want to adopt the open This provides customers with more choices.”
The R9A02G021 MCU product series has made outstanding performance in balancing performance and power consumption. This series of MCUs has a clock speed of up to 48MHz, a standby power consumption of only 0.3µA, and provides 128KB fast flash memory, 16KB SRAM memory and 4KB flash memory for data storage. The products are designed for working environments under harsh conditions and can operate reliably in the range of -40°C to 125°C. In addition, the product is equipped with a standard serial communication interface and digital-to-analog converter (DAC) and analog-to-digital converter (ADC) functions to facilitate high-speed and secure connections to sensors, displays and other external modules. The wide input voltage range of 1.6V to 5.5V makes the R9A02G021 MCU an ideal choice for battery-powered devices.
Key features of the R9A02G021 MCU product family include: RISC-V core, 48MHz clock speed, 128KB code flash, 16KB SRAM (12KB and ECC SRAM 4KB) and 4KB data flash, low power consumption, standard serial communication interface, analog peripherals such as ADCs and DACs, as well as a wide operating temperature range and input voltage range.
The launch of this new product marks Renesas Electronics' further leadership in the RISC-V field and provides embedded system designers around the world with more choices and room for innovation.
