Microcontroller incorporating a floating point unit (FPU), best suited for controlling a single inverter
The RX23T Group is 32-bit 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.

Hardware Design Support
|IBIS/BSDL||IBIS standard simulation data is required for high-speed board design and can be used to run simulations to examine and troubleshoot issues such as waveform reflection, ringing, and so on, before producing the actual board.
BSDL is a data input format supported by most IEEE 1149.1 (JTAG)-compliant tools. The automatic test pattern generation (ATPG) and automatic test equipment functions of these tools facilitate testing.
