Renesas Electronics RX23T 40MHz 32-bit RX MCUs
Renesas Electronics RX23T 40MHz 32-bit RX MCUs are designed for single inverter control. The RX23T allows easy programming in complex inverter control algorithms with the built-in FPU (floating-point processing unit). These features greatly reduce the time required for software development and maintenance. The Renesas Electronics RX23T 32-bit RX MCUs provide an RX200 core that consumes a small 0.45 μA current, in software standby mode (with RAM retention).
The RX23T microcontrollers operate in a wide voltage range from 2.7V to 5.5V, which is useful for inverter control. The MCUs are highly compatible with the RX62T series at the pin arrangement and software level.
