DRV8402 Motor Driver Circuit The main component is the microcontroller dsPIC30F2010, who for its activities needs outside of the power supply voltage also a source of accurate clock pulses. In order to achieve the speed of 30 MIPs, we had to calculate the speed of the desired crystal. Each instruction takes four bars of the hourly pulse and when using the multipliers impulses 16x PLL we get a crystal about the size of 7,3728 MHz. According to the datasheet of the processor is needed to connect to the input of the crystal two capacitors.
