Via is shipping a power-efficient mini-ITX SBC (single-board computer) targeting digital media appliances. The Epia CN, based on a 1GHz-1.3GHz C7 processor and Via's newest desktop chipset, typically consumes 16 Watts, and features a simplified onboard peripheral and I/O set compared to previous C7-based mini-ITX boards. The CN allegedly runs Linux.

The power-efficient CN is Via's second mini-ITX board based on the C7, following the March debut of the performance-oriented Epia EN series (a prototype of which is pictured at right). Whereas Epia EN boards are six-layer PCBs (printed circuit boards) with slightly faster C7-based processors and a truly astounding array of I/O — in particular, I/O aimed at media processing applications — the new CN series boards feature a simpler four-layer design that still uses Via's newest desktop chipset. The CN boards eschew some of the more esoteric peripherals and I/O found in the EN boards, while still supporting advanced media features, such as an S-video port with “DuoView” dual-display capabilities (operation under Linux not confirmed).

The C7 processor that powers both the Epia EN and CN boards is built on 90nm SOI (silicon-on-insulator) process technology, and is being produced at an IBM fab in East Fishkill, New York. Via announced the C7 about a year ago, touting it as “the world's smallest, lowest power, and most secure native x86 processor.” The C7 processors are claimed to draw about half as much power, for the same performance, as Intel's Celeron M chips. Additionally, the C7 chips feature built-in cryptographic accelerators supported by Via's free security tools. Lots more details on the C7 can be found in our earlier story about the Epia EN boards.

Like the Epia EN, the Epia CN boards use a CN700 IGP chipset, which includes a CN700 northbridge and VT8237R Plus southbridge. The CN700 chipset features frontside (processor) and memory buses clocked at 533MHz, built-in Unichrome graphics, a rich variety of media interfaces (albeit some with binary-only Linux drivers), and a low-power design, Via says.

The lower-powered Epia CN boards offer a fair number of onboard peripherals and I/O interfaces. However, compared to the earlier Epia EN, they lack Firewire/IEE1394 pin headers, and have only 10/100 Ethernet, instead of Gigabit Ethernet. Also missing are dedicated digital audio (S/PDIF) I/O ports, LVDS (low-voltage differential signal) connectors for LCD inverters/modules, component video I/O pin headers, SMBus connector, LPC connector, and SIR IrDA header (the CN does have CIR).

Availability

The Via Epia CN1300 appears to be available from stock, priced at about $225, from online retailers such as Logic Supply. The passively cooled Epia CN1000 does not yet appear to be stocked by online retailers, however.
