Evaluation Board Hardware Description
11 Evaluation Board Hardware Description
This EVB consists of a MC33814 Small Engine Control Integrated Circuit (IC), a USB to SPI Dongle
interface, and power conditioning circuitry. All +5 volt VCC power required by the EVB is obtained from
the MC33813 built-in power regulator. A +12V VBAT supply provides the power to the three internal
voltage regulators.
