The RX72T range has achieved an 1160 CoreMark score on EEMBC Benchmarks – the highest level for a 5V MCU operating at 200 MHz.
The RX72T MCUs have dedicated accelerator hardware for the high-speed position control and speed control calculations required for implementing servo motor control in compact industrial robots. This allows the current control loop calculation to be performed in less than 1.5 µs.
Renesas implements only the single-precision floating point trigonometric function (sin, cos, arctan, hypot) and a register bank save function in hardware as dedicated IP to retain flexibility while increasing the calculation speed. The register bank save function increases the speed and precision of interrupt handling, improving the device computation performance. The MCUs also include 200 MHz PWM inverter control timers with up to 4 channels of 3-phase control, 2 channels of 5-phase control or 10 channels of single-phase control.
Renesas provides programs that implement sensorless vector control and encoder vector control. Renesas provides the Renesas Motor Workbench 2.0 for real-time debugging and an RX72T CPU card that supports the 24 V motor control evaluation kit.
The new RX72T MCUs offer an extensive lineup of 5V operation motor control MCUs with excellent software compatibility. This provides a smooth migration path from the new high-end MCUs out to the RX23T (40 MHz), RX24T (80 MHz), and RX66T (160 MHz) MCUs. The RX72T Group is also fully compatible with the RX66T Group incorporating the RXv3 core.
