Arcom has introduced “lite” versions of two XScale-based PC/104 CPU modules. The Viper-Lite and Mercury-Lite support embedded Linux, and are configured for high volume, cost sensitive applications, according to the company.

Viper-Lite

Arcom describes the Viper-Lite (pictured above) as a scaled down version of its PC/104 Viper, a single-board computer (SBC) that supports an embedded Linux development kit from Arcom, as well as a real-time Linux kit from FSMLabs.

The Viper-Lite runs a 200 MHz PXA255 processor instead of 400 MHz, has fewer USB and serial ports, and lacks the PC/104 expansion connector and audio codec. Like the original Viper, it includes a flat panel display controller, CompactFlash slot, and 10/100 Base-T Ethernet.

The device is available in two temperature ranges — -20 to +70 degrees C, and -40 to +85 degrees C. Additionally, it features soldered-on memory for improved reliability, according to Arcom.

Mercury-Lite

The Mercury-Lite is a scaled-down version of Arcom's Mercury board. It has a 266MHz Intel XScale IXP420 processor, instead of a 400MHz IXP425. It features two Fast Ethernet MACs, two high-speed serial ports instead of three, and no USB ports or RS422/485 port. It does have a PCI bus and DMA controller, as well as a real-time clock, and CompactFlash port.

Availability

The Viper-Lite is priced “under $200” in quantities of 100. The Mercury-Lite is priced “below $200” in quantities of 500.
