In addition, 4 operational amplifiers OP/comparators CMP are integrated on-chip, so that the microcontroller has a higher gain bandwidth. With the built-in 6-channel enhanced PWM output with dead-time function, 19-channel 12-bit ADC can be used for BUCK-BOOST circuit , precise control of motors, etc. In addition, a 32-bit hardware multiplier/divider is integrated on the chip, which can calculate the result in 8 clock cycles, which greatly speeds up the operation of control or filtering algorithms, such as PID control operation of integer parameters, or 12-bit ADC value calculation. filter operation.
