With the R9A02G021, Renesas provides designers with a clear and reliable IP migration path for developing a wide range of high-performance, low-cost applications that can be mass-marketed quickly, while eliminating any issues related to proprietary architectures. The R9A02G021 MCUs are ultra-low-power MCUs featuring a single 32-bit processor core operating at up to 48 MHz and delivering a CoreMark of 3.27 per megahertz. Specifically designed for low-power applications, the R9A02G021 MCU family consumes as little as 162 µA/MHz in active mode and 0.3 µA in software standby mode with a wake-up time of 4 µs.
The wide input voltage range of 1.6 to 5.5 V also enables low-voltage and low-current operation, and provides noise immunity, making the devices ideal for battery-powered applications. Other key features of these MCUs include a 12-bit ADC, an 8-bit DAC, on-chip comparators, a temperature sensor, power management functions, multiple clock and timer sources, and safety systems. The R9A02G021 MCUs are compatible with the RTK9FPG021S00001BJ rapid prototyping board, designed for evaluation, prototyping, and development.
