Common-purpose 32-bit MCUs within the R9A02G021 group from Renesas make use of an internally developed RISC-V CPU core. Renesas has designed and examined the brand new RISC-V core independently and carried out it in a business product that’s obtainable worldwide.
R9A02G021 MCUs allow embedded methods designers to develop low-power, cost-sensitive functions primarily based on the RISC-V open-source instruction set structure (ISA). The gadgets goal such finish markets as IoT sensors, client electronics, medical gadgets, small home equipment, and industrial methods. They’re additionally supported by a full-scale growth surroundings and a community of toolchain companions.
The CPU core runs at 48 MHz and achieves a efficiency score of three.27 CoreMark/MHz. Energy consumption is 162 µA/MHz when lively, dropping to simply 0.3 µA in standby with a wakeup time of 4 µs. Different options of the R9A02G021 group embody:
- Reminiscence: 128 KB code flash, 16 KB SRAM, and 4 KB information flash
- Serial communications interfaces: UART, SPI, I2C, SAU
- Analog peripherals: 12-bit ADC and 8-bit DAC
- Temperature vary: -40°C to 125°C
- Working voltage vary: 1.6 V to five.5V
Packaging choices for the R9A02G021 MCUs embody 16-pin WLCSP and 24-pin, 32-pin, and 48-pin QFN. Gadgets can be found now via international distributors.
