Chapter 1:

ML630 Board Features and Operation

The CP2103 supports an I/O voltage range of 2.5V on the ML630 board. The connections 
between FPGA U1 and CP2103 should use the LVCMOS25 I/O standard. UART IP (for 
example, Xilinx® XPS UART Lite) must be implemented in the FPGA logic. FPGA U1 
supports the USB to UART bridge using four signal pins:

•

Transmit  (TX)

•

Receive (RX)

•

Request to Send (RTS)

•

Clear to Send (CTS)

Connections of these signals between the FPGA and the CP2103 at U26 are listed in 

Table 1-8

.

The bridge device also provides as many as four GPIO signals that can be defined by the 
user for status and control information (see 

Table 1-9

).

A royalty-free software driver named Virtual COM Port (VCP) is available from Silicon 
Laboratories. This driver permits the CP2103 USB to UART bridge to appear as a COM 
port to the host computer communications application software (for example, 
HyperTerminal or TeraTerm). The VCP driver must be installed on the host computer prior 
to establishing communications with the ML630 board.
