Mouser is offering the first general-purpose 32-bit MCUs featuring Renesas' proprietary RISC-V processor core.

Mouser Electronics announced today that it is now stocking the R9A02G021 low-power microcontroller (MCU) from Renesas Electronics.

The R9A02G021 is Renesas' first general-purpose 32-bit MCU family built on the company's proprietary RISC-V processor core, designed to support a wide range of end markets, including IoT sensors, consumer electronics, medical devices, small appliances, and industrial systems.

It provides a versatile platform for developing power- and cost-efficient applications using an open-source instruction set architecture (ISA). Renesas said the R9A02G021 “provides a stable IP migration path for developing a wide range of high-performance applications, enabling designers to quickly enter the mass production market without worrying about proprietary architectures.”

The R9A02G021 microcontroller, available from Mouser, is an ultra-low-power MCU with a single 32-bit processor core that runs at up to 48 MHz and delivers 3.27 CoreMark performance per megahertz (MHz).

Designed specifically for low-power applications, the R9A02G021 MCU family consumes just 0.3µA in software standby mode and 162µA/MHz in active mode with a 4µS wake-up time.

Additionally, it supports low-voltage, low-current operation over a wide input voltage range of 1.6 to 5.5 V and is noise-resistant, making it an ideal device for battery-powered applications.

The memory consists of 128KB of code flash memory, 4KB of data flash, and 16KB of SRAM, and also includes a 128-bit unique ID.

Additionally, Renesas RISC-V MCUs feature a 12-bit ADC, an 8-bit DAC, on-chip comparators, a temperature sensor, power management functions, multiple clock and timer sources, and safety features. The devices also offer simplified SPI, UART, and I2C connectivity, as well as two serial array units (SAUs) that support an I2C bus interface and a remote control signal receiver.

The R9A02G021 microcontroller is available in various QFN packages ranging from 48, 32, 24 and WLCSP16. The R9A02G021 MCU is also supported by the RTK9FPG021S00001BJ rapid prototyping board designed for evaluation, prototyping and development, in addition to access to Renesas' complete ecosystem of free tools, including the e2 Studio IDE and industry-leading tools from IAR and SEGGER.
