A33M116/A33M114 are 32-bit high-performance microcontrollers with up to 256 KB 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 two 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 various interfaces, such as UART, SPI, and I2C, and is equipped with four OPAMPs with comparator functions.
