HT66FM5440 Description

The BLDC Motor Flash MCU HT66FM5440 provides PWM configuration flexibility and plete protection mechanism which are necessary for brushless DC motor applications. The device uses the HT8-1T architecture to achieve one oscillation cycle for one instruction. With the integrated 16MHz oscillator, executing a single instruction only needs 0.0625μs.
