Renesas Launches RX72T Group to Expand MCU Options for Servo Control

Renesas Electronics introduced the RX72T Group of 32-bit motor control microcontrollers (MCUs) with dedicated hardware accelerator IP to perform the complex, high-speed computations required for motor control in robots and other industrial equipment. The RX72T Group delivers superior performance, achieving an 1160 CoreMark score as measured by EEMBC® Benchmarks – the highest level for a 5V MCU operating at 200 MHz.

Servo systems are becoming increasingly popular and the demand for compact industrial robots is also rising. To implement the complex motions required by industrial robots, high-precision control of the position, direction, speed, and torque of the motor is required.

The RX72T MCUs include dedicated accelerator hardware that enables 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, providing a new option for users to independently develop servo systems where previously they only had the option of purchasing existing servo systems (more info).
