STEVAL-PCC020V1 tool interfaces any Windows® based PC with HVDPS products such as STNRG011. It is fundamentally a bidirectional bridge between USB and I²C/UART buses.
The STEVAL-PCC020V1 is self-supplied 5 V from the USB port. An isolated DC-DC module provides the correct supplies to the remaining electronics. The board is also able to provide the target STNRG device with a VCC voltage to program the NVM (if supply is less than 17 V).
Communication between the STEVAL-PCC020V1 and the PC is managed by a standard serial peripheral, converting the USB connection into a virtual COM port. UART RX and TX signals are then isolated with opto-couplers and connected to the STM32 microcontroller, so the USB port and the rest of the board remain isolated from the mains. The microcontroller handles bridging between the host UART and target UART/I²C buses and protocols.
