	Interface
	Your choices are...
	CompactPCI (cPCI) / PXI		Compact PCI (cPCI) is a high-performance industrial bus that uses the electrical standards of the PCI bus and is packaged in a Eurocard. Specifications for the CompactPCI bus are developed and maintained by the PCI Industrial Computers Manufacturers Group (PICMG). cPCI buses are used extensively in systems that require high speed data transfers. Examples include data communication routers and switches, real-time machine control, real-time data acquisition, military systems, etc.
	Fibre Channel		Fibre channel is a high-speed, serial data transfer architecture that uses links of twisted-pair, coaxial or fiber optic cable. Small computer system interface (SCSI) devices can use fibre channel arbitrated loop (FC-AL), the most popular fibre channel typology. Using optical fiber, FC-AL supports full-duplex data transfer rates of 100 Mbps. Eventually, FC-AL is expected to replace SCSI in high-performance storage systems.
	IEEE 1394 (FireWire®)		IEEE 1394 or FireWire® is an interface standard adopted by the Institute of Electrical and Electronics Engineers (IEEE) for very fast digital data transfers such as streaming video. IEEE 1394 connectors are used to transmit and receive data among FireWire devices, and are designed to replace external high-speed peripheral connections to personal computers, including hard disks, CD-ROMs, DVDs, graphics cards, high-speed scanners, direct video, monitors, etc. Tiny, robust FireWire connectors will also become important parts of home entertainment, communication, and appliance networks. FireWire is a registered trademark of Apple Computer, Inc.
	I2C		Inter-integrated circuit (I2C) bus is a two-wire, low to medium speed, communication bus.
	PCI		Peripheral component interconnect (PCI) is a local bus system designed for high-end computer systems. PCI buses transfer 32 or 64 bits of data at a clock speed of 33 MHz. They also support 3 to 5 critical peripherals, which are either integrated directly onto the motherboard or added via expansion cards. PCI buses fully support cards that were developed for standard I/O buses.
	PCI Express		PCI express (PCIe) fits common system architectures, provides greater speed and independence, and increases bandwidth and scalability. PCIe offers 4 Gbps of peak bandwidth per direction and 8 Gbps of concurrent bandwidth. PCIe is referred to as a third-generation input / output (3GIO).
	PCMCIA / CardBus		PCMCIA devices (PC cards) are credit-card-sized peripherals predominantly used in laptop computers. The PCMCIA adapter takes the place of a COM port on a standard bus. The card is plugged into a 68-pin host socket that is connected either to the motherboard or an expansion bus. An adapter then translates the PCMCIA signals into signals usable by the computer's bus.
	PCM		Pulse code modulation (PCM).
	PECL		Positive emitter coupling logic (LVPECL).
	RS232		RS232 is a standard interface approved by the Electronic Industries Association (EIA) for connecting serial devices. This popular, serial communications standard provides asynchronous communication capabilities with hardware flow control, software flow control, and parity checking. Most gears, instruments with digital control interfaces, and communication devices have an RS232 interface. The typical transmission speed for RS232 is 9600 bps at 15 m.
	RS422		RS422 supports multipoint connections whereas RS423 supports only point-to-point connections. RS422 provides much longer transmission distances than RS232, but less signal line. RS422 uses a differential transmission technology and provides high-speed transmissions up to 10 Mbps over a maximum transmission distance up to 1.2 km at 110 kbps.
	RS485		RS485 is almost identical to RS232 except that transmissions are three-way rather than two-way. RS485 is often used in applications where a single controller needs to control multiple devices. Up to 64 devices may be connected with RS485. An enhanced version of RS422, RS485 is compatible with the RS422 interface and provides a two-wire bus topology. Using an RS485 two-wire bus provides a very inexpensive network system; however, RS485 defines only the electronic signal specifications. Consequently, users must define the software protocol for RS485 two-wire communications.
	SLIC		Subscriber line interface circuits (SLIC).
	SPI		Serial peripheral interface (SPI).
	UART		Universal asynchronous receiver transmitter (UART).
	USB		Universal serial bus (USB) is a 4-wire, 12-Mbps serial bus for low-to-medium speed peripheral device connections to personal computers (PC), including keyboards, mice, modems, printers, joysticks, audio functions, monitor controls, etc. The USB design is standardized by the USB Implementers Forum (USBIF), an organization that includes leading companies from the computer and electronics industries. The current USB specification is USB 2.0, which supports data transfer rates of up to 480 Mbps.
	USB On-The-Go		USB on-the-go (USB OTG) is an expanded USB 2.0 specification. It is designed to overcome the shortcomings of the original USB 2.0 standard.
	VME		VersaModule Eurocard bus (VMEbus) is a popular, 32-bit bus used in industrial, commercial and military applications. The VMEbus is based on the VME standard, which defines mechanical specifications such as board dimensions, connector specifications and enclosure characteristics, as well as the electronic specifications for sub-bus structures, signal functions, timing, signal voltage levels, and master/slave configurations. The VMEbus uses 3U and 6U Eurocard, rugged circuit boards that provide a 96-pin plug instead of an edge connector for durability. Several VMEbus varieties are available.
	Other		Other unlisted or proprietary interface types.

Packaging

	IC Package Type:
	Your choices are...
	Bare Die		Devices are sold in semiconductor die form. They do not have a case or packaging.
	BGA		Ball-grid array (BGA) places output pins in a solder ball matrix. Generally, BGA traces are fabricated on laminated (BT-based) substrates or polyimide-based films. Therefore, the entire area of substrates or films can be used to route the interconnection. BGA has another advantage of lower ground or power inductance by assigning ground or power nets via a shorter current path to PCB. Thermally enhanced mechanisms (heat sink, thermal balls, etc.) can be applied to BGA to reduce the thermal resistance. The sophisticated capabilities make BGA the desirable package to implement electrical and thermal enhancement in response to the need for high power and high speed ICs.
	FCBGA		Flip chip ball-grid array (FCBGA) uses a combination of flip chip and ball grid array features. FCBGA enables short electrical paths for high frequency applications. The simultaneous soldering of all joints in one pass through a reflow furnace facilitates the mounting of packages with thousands of solder joints.
	PBGA		Plastic ball-grid array (PBGA) is the general terminology for the BGA package adopting plastic (epoxy molding compound) as the encapsulation. According to JEDEC standard, PBGA refers to an overall thickness of over 1.7 mm.

	SBGA		Super ball-grid array (SBGA) provides a high-power BGA package with a very low profile. With SBGA, the IC is directly attached to an integrated copper heatsink. Since the IC and I/O are on the same side, signal vias are eliminated, providing a significant improvement in electrical performance (inductance).

	DIP		Dual in-line package (DIP) is a type of semiconductor component packaging. DIPs can be installed either in sockets or permanently soldered into holes extending into the surface of the printed circuit board. The pins are distributed into two parallel lines along opposite site of the rectangular package. There are several types of DIP packages, such as Ceramic Dual in-line package (CDIP), Plastic Dual in-line package (PDIP), and Shrink Plastic Dual in-line package (SPDIP).
	CDIP		Ceramic dual in-line package (CDIP) consists of two pieces of dry pressed ceramic surrounding a "DIP formed" lead frame. The ceramic / LF / ceramic system is held together hermetically by frit glass reflowed at temperatures between 400° - 460° centigrade.
