Additional Information
The PC/104-
Plus
is electrically equivalent to the 33 MHz PCI bus (and generated by the
TI XIO2001 PCIe to PCI bridge chip) and terminated to a 120-pin non-stack-through
connector. The input voltage of the connector can be configurable between 5VDC and
3.3VDC with a jumper. The interface does not support hot-swap capability.
The interface is PC104/Plus v2.0 compliant.
Connector
120-Pin SAMTEC type ESQT-130-G-Q-368, solder-tail (short) pins
7.10.23 MC1 and MC2 MiniPCI Express
The EPX-C414 includes MiniPCIe sockets at MC1 and MC2.
These support a variety of peripherals as available in this format. Though the sockets
support other devices, they are most often used to add wireless Ethernet cards from
Broadcom, Foxconn (Atheros), or others.
The two MiniPCIe connects support PCIe and USB. One connector also alternatively
supports an mSATA device in this socket. A sense circuit identifies the type of device
present and auto-switches to handle either type.
MC1 supports PCIe only.
MC2 supports either mSATA or PCIe. Use jumper “JPMSATA” on page 45 to select
which device to use with MC2.
NOTE
If JPMSATA is connected 1-2, MC2 is configured for PCIe operation and the pinout in
the table below is correct.
When JPMSATA is connected 2-3, pins 23, 25, 31, and 33 change to SATA_RXp,
SATA_RXn, SATA_TXn, SATA_TXp, respectively. This alternate pinout for CM2 is
shown is parentheses.
