RX62T Motor & Inverter Control

The Renesas RX62T Group of high-performance microcontrollers with a maximum operating frequency of 100MHz are designed for motor control. They are equipped with multifunction timers (MTU, GPT), high-speed 12-bit A/D converter, and 10-bit A/D converter for facilitating motor control. The products also incorporate many safety features to comply with the IEC60730 safety standard for home appliances. In addition to a maximum of 256KB flash and 16KB RAM on-chip memory, they have a maximum of 32KB of on-chip flash memory for data storage. 64-pin to 112-pin packages are available.

RX62T Overview

RX62T Motor Control Image

High-performance CPU and FPU capability, and advanced analog and timer peripherals, make the RX62T an ideal solution for inverter and motor control applications. Renesas can help you develop your motor control solution with kits and firmware that support many kinds of motor control, including ultra-quiet, energy- efficient, and high-precision three-phase sensorless vector control.

In the home appliance example shown here, the RX62T is driving two three-phase motors simultaneously using its advanced PWM timers. These timers are well suited for Brushless DC three-phase motors by having complimentary PWM outputs with automatic dead-time insertion, an emergency "Shut-down" (stop) input, and quadrature encoder inputs for speed and direction feedback.

The RX62T's advanced analog subsystem with multiple sample-hold circuits enables sampling of three simultaneous current measurements. It also offers programmable operational amplifiers and integrated window comparators to eliminate external components. The 12-bit ADCs have a fast 1μsec conversion time, can be triggered by the PWM timers, and provide self-diagnostic capability.

RX62T MCUs provide improved motor/inverter control timers and enhanced analog peripherals for implementing very precise motor control and positioning applications. The MTU3 and GPT timer peripherals enable one MCU to control three motors simultaneously. An FPU and improved analog functions make these MCUs ideal for use with three-shunt or single-shunt vector-type motor control methods.
