Renesas Unveils Next-Generation RISC-V MCUs: Revolutionizing Embedded Systems

The R9A02G021 group of general-purpose 32-bit MCUs by Renesas introduces a significant advancement by integrating an internally developed RISC-V CPU core. This core, designed and tested independently by Renesas, is now incorporated into commercial products available worldwide.

These MCUs cater to embedded systems designers, offering opportunities to develop low-power and cost-effective applications utilizing the RISC-V open-source instruction set architecture (ISA). Targeting various end markets such as IoT sensors, consumer electronics, medical devices, small appliances, and industrial systems, these devices come with comprehensive support, including a full-scale development environment and collaboration with toolchain partners.

Key features of the R9A02G021 group include a 48 MHz CPU core delivering 3.27 CoreMark/MHz performance rating. Remarkably, the power consumption is impressively low, with 162 µA/MHz in active mode and a mere 0.3 µA in standby mode, with a quick wakeup time of 4 µs. Additional specifications encompass a memory of 128 KB code flash, 16 KB SRAM, and 4 KB data flash, along with various serial communication interfaces and analog peripherals. The operating temperature range spans from -40°C to 125°C, with an operating voltage range of 1.6 V to 5.5V.

Packaging options for the R9A02G021 MCUs are versatile, including 16-pin WLCSP and 24-pin, 32-pin, and 48-pin QFN. These devices are readily available through global distributors, promising enhanced efficiency and performance for a wide array of embedded system applications.
