A33M116/A33M114 are 32-bit high-performance microcontrollers with up to 256KB of flash memory. It is a powerful microcontroller which provides effective solutions to various home appliances which require both low power consumption and high performance. The MCU is equipped with two three-phase PWM generators capable of controlling two inverter motors. The MCU’s three high-speed 12-bit analog-to-digital converters (ADCs) are capable of processing motor driving information coming in through analog channels. It also supports external communication through a variety of interfaces such as UART, SPI and I2C, has four analog comparators and four programmable gain AMPs.
