Description

The RX23T Group is a 32-bit microcontroller suited for single inverter control and has a built-in floating-point processing unit (FPU) that enables users 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 0.45μA. RX23T microcontrollers operate in a broad voltage range from 2.7V to 5.5V, which is useful for inverter control, and are highly compatible with the RX62T Group at the pin arrangement and software level.
