The RX23T Group is 32bit microcontroller and suited for single inverter control and has a built-in FPU (floating-point processing unit) that enables it to easily program complex inverter control algorithms. This helps to greatly reduce the man-hours required for software development and maintenance. Furthermore, thanks to the RX200 core the current consumed in software standby mode (with RAM retention) is a mere 0.45 μA. RX23T microcontrollers operate in a broad voltage range from 2.7 V to 5.5 V, which is useful for inverter control and are highly compatible with the RX62T Group at the pin arrangement and software level.
