Xilinx Virtex-7 VC7222 User Manual page 35

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 VC7222 board.
FPGA Mezzanine Card HPC Interface
Callout
The VC7222 board features two high pin count (HPC) connectors as defined by the VITA
57.1 FPGA Mezzanine card (FMC) specification. The FMC HPC connector is a 10 x 40
position socket. See
of signal names to pin coordinates.
FMC1 HPC connector JA2 provides connectivity for:
•
•
FMC2 HPC connector JA3 provides connectivity for:
•
•
Note:
The FMC HPC connectors on the VC7222 board are identified as FMC1 at JA2 and FMC2 at
JA3. The connections for each of these connectors are listed in
respectively.
