Product overview

Description

The STEVAL-PCC020V2 is a board with the purpose to interface a Windows® based PC with HVDPS products such as STNRG01x or ST-ONE. It is basically a bidirectional bridge between USB and I²C/UART buses.

The board is self-supplied through the 5 V coming from the USB port. An isolated DC-DC module is available to provide the correct supplies to the remaining devices. The board is also able to provide the requested VCC voltage to the target device to program the NVM or the flash memory parameters.

A standard USB-to-serial bridge manages the communication between the interface board and the PC. Thus, the USB connection is converted into a virtual COM port.

UART Rx and Tx signals are then isolated thanks to the opto-couplers and connected to an on-board STM32 MCU, keeping the USB port and the remaining devices isolated from the mains.

The microcontroller is in charge of making the bridge between the host UART and the target UART/I²C buses and protocols (dedicated GUIs are also available to handle STNRG01x or ST-ONE specific protocols and features).

The board also offers a dedicated connector able to support autonomous programming for mass production purposes (for example, update of the NVM content using automation tools instead of a standard USB connection).
