* General Description 
 

In comparison to SONiX's previous 8-bit MCUs, the SN8F5700 series stands out with market-leading features including three individual sets of 16-bit asynchronous 32MHz High Speed PWM Generator and support for up to 6-channel PWM output. SN8F5700 can easily define cycle and duty through registers.

The max speed of cycle is 16MHz, the max resolution is 16-bit with dead-band/invert function. The PWM can easily be applied to BLDC motor Six Step Square Wave/Sine Wave controls, wireless power charger coil driving and MOS control appliance.

Further, SN8F5700 series offers a wide range of benefits by combining internal interrupt and high precision SAR ADC therefore the function of PWM can be utilized for Brushless Direct Current Motor (BLDC Motor) and for Hall-sensor and sensor less applications.
