|GSC has numerous I/O cards in true PC/104-Plus form factor and any I/O card can be easily converted to true PC/104-Plus.|
Also, the large variety of PMC I/O cards from GSC can be used on a PC/104-Plus stack by using PMC-to-PC/104Plus adapters. These adapters can be purchased as stackable or non-stackable,
and with or without the ISA connector.

All standards can be downloaded without charge. All standards
administered by the Consortium use small (3.6 x 3.8 in), self stacking
PC/104, PC/104-Plus or PCI-104 I/O modules with 104-pin ISA and/or 120-pin
PCI bus connectors for I/O expansion. This unique stacking technology
allows multiple modules to be added to a system without the burden of
backplanes and card cages.
The PCI/104-Express specification establishes a standard to use high speed
PCI ExpressR bus in embedded applications. Incorporating the PCI Express bus within the industry proven PC/104
architecture brings many advantages for embedded applications including fast data transfer, low cost due to PC/104's unique self-stacking bus, and high reliability due to PC/104's
Introduction to PCI/104-Express
The main objective in defining an addition of PCI Express to PC/104 was to
preserve the attributes that have made PC/104 so successful in embedded
Compact: 3.6 by 3.8 inches (90 x 96 mm) module size;
Self-stacking: expands without backplanes or card cages;
Rugged, reliable connectors: reliable in harsh environments;
Four-corner mounting holes: resistance to shock and vibration;
Fully PC compatible: reduced development costs and time-to-market.
In addition, the design had to support automatic detection of up or down
stacking and had to have automatic link shifting to allow simplified,
universal add-on module designs.
The PCI/104-Express design approach provides a consistent and
interchangeable path for the stackable PC architecture across the PC/104
Embedded Consortium's 104, EPIC, and EBX form factors.
PCI Express bus connector:
PCI/104-Express Specification Overview/strong>
Four x1 PCIeR Links
One x16 PCIe Link (optionally configurable as two x8 Links, two x4 PCIe Links, or two SDVO Interfaces)
Power: +3.3V, +5V, +12V, and ATX power and control signals and Power OK.
Summary of the basic specs of PCI/104-Express modules:
Number of PCI Express modules per stack -- 4 x1 and 1 x16 (host may
configure as two x4 or x8);
Stack direction - Stack up or stack down;
Data throughput PCI bus - 132 M Bytes/sec (26 times ISA);
Data throughput single x1 Link - 500 M Bytes/sec (4 times PCI);
Data throughput x16 Link - 8,000 M Bytes/sec (60 times PCI);
Total data throughput all Links - 10,000 M Bytes/sec (75 times PCI);
PCI Express bus power +5V power capability - 84 watts;
PCI Express bus power +12V power capability - 100 watts;
The PCI Express connector was specifically designed to match the PC/104
standard 0.600 inch (15.24mm) stacking height and standoff tolerances.
PC/104 stackable embedded PCs have followed the desktop PC.
PCIe/104 is PCI/104-Express without the PCI bus. Since PCI Express is
based on PCI technology, a PCI Express to PCI Bridge is a straightforward.
A comparison between a PCI/104-Express CPU and Stack and a PCIe/104 CPU and
stack shows that both easily support PCI Express and PCI add-in cards.
Copies of the PCI/104-Express Specification are available to individuals
and companies developing embedded systems. For further information, contact
the PC/104 Embedded Consortium at www.pc104.org.
The PC/104 Embedded Consortium maintains the PC/104T, PC/104-PlusT, and
PCI-104T specifications on the 104T form factor as well as the
specifications for the EPICT and EBXT form factors.
Other PC/104 Specifications
PC/104 is the original specification. It defined the 104 form factor at
3.550 x 3.775 inch. PC/104-Plus added PCI bus to classic PC/104 on the
104 form factor.
PCI-104 is the same as PC/104-Plus, except it does not have an ISA
The PCI/104-Express & PCIe/104 specifications continue to follow the desktop
Where Does PCI/104-Express Fit?
PC/104 supports ISA only
PC/104-Plus supports PCI and ISA
PCI-104 supports PCI only.
