Renesas Electronics has launched a family of microcontrollers with a hardware accelerator where a single MCU can simultaneously control up to two brushless DC (BLDC) motors.
RA6T2组单片机测控are accelerator and peripherals designed specifically for motor control designs in home appliances, smart home, industrial and building automation, as well as inverter control.
嵌入式硬件加速器包括三角功能单元（TFU）和无限脉冲响应（IIR）滤波器。TFU执行高速计算，而无需查找表，从而有效使用ROM。IIR过滤器提供的系数设置方法可以从现有算法中简化移植。
The family is based on the 240MHz ARM Cortex-M33 core with 512 KB Flash ROM; 64KB SRAM; 16KB Data Flash and peripherals optimized for high performance and precision motor control in order to reduce bill of materials (BOM) cost while boosting performance.
This includes two independent 12bit ADC units offer high-speed conversion with a maximum speed of 0.16 µsec and include a simultaneous sample and hold function for three channels to detect the three-phase current of a motor.
There are also programmable gain amplifiers that can set the gain according to the input voltage range and analog components that were previously external are incorporated, including comparators which detect abnormal voltage input and over current.

An adjustable PWM timer makes it easy to port existing algorithms and in cooperation with other analog functions, provides a PWM output cutoff safety function in the event of an abnormality. With these features, a single RA6T2 MCU can simultaneously control up to two brushless DC (BLDC) motors.
