STEVAL-PCC004V1演示板由一个微型B-USB接口，一个USB控制器，USB收发器，2个2到4解复用器和所有所需的分立元件（上拉电阻，串联电阻和电源电容）。该演示板从USB微型B供电或，任选地，从外部供给。收发器STUSB02连接在微控制器的USB通信线路。For demonstration purposes, the USB microcontroller used is the ST72F63BE2 8-bit microcontroller. The STUSB03 connected to a USB controller is ideal for use in mobile phones, digital cameras, printers, PDAs, etc. All hardware omponents except the transceiver IC are the same for the STEVAL-PCC003V1 and STEVALPCC004V1 demonstration boards. The demonstration board is comprised of one mini-B USB connector, a USB controller, a USB transceiver, two 2-to-4 demultiplexers and all required discrete components (pull-up resistors, series resistors and power supply capacitors). The device can be configured through a set of jumpers and the main signals can be accessed through test points. The demonstration board is powered from a USB mini-B or, optionally, from an external supply. The transceiver STUSB02 is connected at the USB communication lines of the microcontroller.
