This introduction presents general information about the PC/104 architecture and the MiniModule 1394 (FireWire) expansion board. After reading this chapter you should understand:

• PC/104 and PC/104-Plus Concept
• MiniModule 1394 Architecture and Features
• Major components and Connectors
• Specifications

# PC/104 Architecture

The PC/104-Plus architecture affords a great deal of flexibility in system design. You can build a simple system using only a CPU/Controller, such as an Ampro Little Board or CoreModule SBC, which provides the processor, memory, and input/output device connections (keyboard, mouse, serial, parallel, floppy drive, and IDE drives). To expand the I/O capability of a simple system, simply add self-stacking PC/104 and PC/104-Plus expansion boards, such as Ampro’s MiniModules, to provide additional capabilities, such as:

• Additional serial and Ethernet ports
• USB or IEEE 1394 (FireWire)
• PC card interfaces
• Sound cards

PC/104-Plus expansion boards can be stacked with the CPU Board avoiding the need for card cages and backplanes. The PC/104-Plus expansion boards can be mounted directly to the PC/104 and PC/104-Plus connectors of the target CPU Boards. PC/104-Plus compliant boards can be stacked with an inter-board spacing of \~0.66 inches so that a 3-board system fits in a 3.6 inch by 3.8 inch by 2.4 inch space. See Figure 3-1.

One or more PC/104-Plus boards can be installed on the CPU board‘s expansion connectors. When installed on an Ampro CoreModule or Little Board, the expansion board fits within the CoreModule or Little Board outline dimensions. Most MiniModule products have stackthrough connectors compatible with the PC/104-Plus Version 2.1 specification. Each additional board increases the thickness of the package by 15mm (0.66”).

# PC/104 Bus Interface (P1A,B,C,D)

The PC/104 Bus uses a 104-pin 100mm header interface. This interface header will carry all of the appropriate PC/104 signals operating at clock speeds up to 8MHz. The interface header is located on the both the top and bottom of the board.

# NOTE

The PC/104 Bus connector is only used as a pass through connector to other boards in the stack and has no connections to the MiniModule 1394 expansion board except the +5V and ground connections

Notes: The shaded area denotes power or ground. The signals marked with \* = Negative true logic.

# Auxiliary Power Interface (J5)

The MiniModule 1394 draws its power from the PC/104-Plus bus connector and only requires +5 volt input power, but uses the +12 volts for cable/bus power only. The +5V is used to generate +3.3V on board. )

• +5VDC +/- 5% @ 0.05 Amps
• +12VDC +/- 5% @ &lt; 1.5 Amps (Used for IEEE 1394 cable/bus power only)

If additional +5V or +12V power is required to power IEEE 1394 devices, it can be provided by the auxiliary power connector (J5). The auxiliary power connector uses a 10-pin header with 0.100” spacing. The auxiliary power connector (J5) supplies the voltages listed in Table 4-8 directly to the board for external use:

Table 4-8 gives the signals for power supply pin-outs and Table 4-9 provides the pin arrangement.
