RX26T 32-Bit MCUs

Renesas' RX26T 32-bit RX motor control MCUs are ideal for connecting customers’ applications with networking and sensors with the expansion of IoT technology, supporting built-in functions that contribute to the reduction of external components. Their small packages are suited for mounting in space-saving and miniaturization of enclosures.

The RX26T series with 120 MHz operating frequency RXv3 core succeeds the RX24T/RX24U. It comes equipped with Flash ROM up to 512 KB and a maximum 64 KB RAM, and timers/analog functions that realize dual motor plus PFC control. Additionally, they are equipped with dual-bank functions, security functions (TSIP-Lite), and communication functions (MIPI I3C Basic^SM/CAN FD) supporting next-generation standards. Higher processing performance is required to implement high-efficiency control for multiple-motor and PFC software control. RX26T realizes high performance by supporting operation frequency improvement (80 MHz to 120 MHz) from conventional product RX24T/RX24U, Renesas proprietary RXv3 (721 CoreMark), Flash 120 MHz no-wait access, and arithmetic unit for trigonometric functions (TFU). As for motor control function, the timer function supports 120 MHz PWM (3-phase complementary 2ch+ single-phase complementary 2ch). The analog function is equipped with three 12-bit A/D converters, including two 3-channel simultaneous sample-and-hold circuit units. This realizes dual motor by field-oriented control (FOC) with a three-shunt method and PFC control, which was impossible with the conventional product (RX24T).
