STEVAL-PCC011V1

STEVAL-PCC001V1 Full speed USB to serial bridge based on ST72F65 Data Brief Features ■ Communication speeds implemented (baud/s): 2400, 4800, 9600, 14400, 19200, 28800, 38400, 56000, 57600, 115200, 128000, 256000 ■ Half-duplex communication ■ 8-bit or 7-bit data + 1-bit parity (even/odd) STEVAL-PCC001V1 Description This evaluation kit demonstrates the use of the USB full-speed microcontroller ST72651 as a bridge between the USB and the RS232 interface, providing an additional serial port on computers equipped with USB. In addition, this evaluation kit demonstrates a simple method for connecting the USB microcontroller ST72651 to the PC without need of a proprietary driver. Several generalpurpose input/output pins of the ST72651 are provided on the external connector, thus providing a way to connect additional circuitry and allow customized USB applications. The evaluation board can be reprogrammed easily with a user code through the in-circuit communication (ICC) connector October 2007 Rev 1 For further information contact your local STMicroelectronics sales office. 1/4 www.st.com 4 Board schematic 1 STEVAL-PCC001V1 Board schematic Figure 1.
