[. . . ] . 3 VIA Pico-ITX Form Factor Small is Beautiful VIA VT6047 Pico-ITX mainboard reference design has been specifically developed to be powered by the energy efficient VIA processor platforms, such as the VIA C7 or fanless VIA Eden processor. The VIA VT6047 Pico-ITX mainboard reference design also features another significant silicon miniaturization advance: one of the new breed of VIA's system media processors, all-in-one digital media IGP chipsets with a powerful array of core logic, multimedia, connectivity and storage technologies within a very highly integrated single-chip package. Table 1 provides a summary of the main features and benefits of the Pico-ITX mainboard form factor. Table 1: Pico-ITX Mainboard Feature & Benefit Summary Features Ultra-compact 10cm x 7. 2cm Board Size Rich I/O Integration Benefits Enables small footprint system designs Reduces overall system costs Support for complete range of I/O standards: USB, COM, DVI, LVDS, 10/100Mbps Ethernet, etc Reduces overall system costs Ultra low power consumption Passive (fanless) cooling Enables more compact system designs Saves system space Enables fanless silent PC designs due to its low heat characteristics Reduces overall system costs Enhances reliability VIA Processor Platform Slimline 30W Power Supply Copyright © VIA Technologies, Inc, 2007.

Standard PC computing and communicating functionality for business, academic and personal use can be catered for in smaller than ever packages with the Pico-ITX, even into portable devices for the handbag or briefcase. The Pico-ITX mainboard form factor was also designed to bring the performance of x86 to the very broad field of embedded design, which underpins almost every aspect of daily life. Automation, display, retail management, casino gaming, traffic management, productivity, signage and many more embedded information and entertainment applications can be given higher levels of intelligence, and can now be built into smaller chassis with the Pico-ITX. The new Pico-ITX mainboard form factor has been specifically designed for integration in ultra small footprint chassis, including a growing number of embedded PC reference systems, such as that shown in Figure 1. Figure 1: Embedded PC Reference Design The Embedded PC reference design is a small, quiet and inexpensive entry-level computing platform spanning price points from US$299 to US$499. It is optimized for mainstream Internet applications and services as well as common productivity, education, storage and entertainment applications. The Embedded PC is fully compatible with standard x86 hardware and software, thus offering the advantage of flexibility, connectivity, upgrade-ability, and, with the VIA C7 processor, quiet operation.

VIA's Mini-ITX form factor, which celebrated its 5th anniversary of commercial availability as the first VIA EPIA mainboard in February of this year, has been enthusiastically adopted by both developers and hobbyists alike and fostered a whole community dedicated to small form factor design, with multiple vendors offering this form factor in both the PC and embedded industries, and a broad and mature infrastructure in place for chassis and other accessories. The Nano-ITX is following in its footprints, having been well received by the embedded market. [. . . ]
