Board-to-Board I/O Connector
The board features a 120-pin PCI-104
-
standard connector which connects the plug-
on module (CPU) with the carrier card and thus leads all important I/O signals to
peripheral connectors. The type of I/O depends on the FPGA configuration of the
A14C, which is very flexible and can contain a number of FPGA IP cores. For more
information on the FPGA, please refer to
Chapter 3 FPGA on page 82
.
This manual describes the standard factory FPGA configuration that is used on
model 01A014C00. (See also
Chapter 3.3 Standard Factory FPGA Configuration on
page 92
.) This version of the A14C provides the following interfaces:
• IDE
• UART COM10
• GPIO (40 lines)
• Miscellaneous functions
You can use FPGA signals also via rear I/O on VME connector P2.
Please note that
PMC I/O signals are directly connected to connector P2. If you use FPGA I/O
signals (e.g. COM10, GPIO) via P2, you must make sure that these signals do
not interfere with PMC I/O signals, since this may cause damage to the CPU
board.
See
Chapter 2.16.16.1 Rear I/O using VMEbus P2 on page 77
for more
details and for pin assignments of P2.
