RX66T 32-Bit MCUs

Renesas RX66T 32-Bit MCUs are the first members of Renesas flagship 32-bit RX MCU family based on the third-generation RXv3 CPU core. These MCUs are optimized for motor control and address real-time performance and enhanced stability. These are helpful for inverter control in next-generation smart factory equipment and smart home appliances. These MCUs also provide the extra processing capacity needed for embedded AI in next-generation designs. The RX66T MCU series help further accelerate the use of intelligent endpoints using real-time e-AI performance to drive smarter appliances and improve production efficiency in smart factories.
