Industrial and commercial embedded computing devices that require ultra low power consumption

With its signature fanless operation, the VIA Eden™ processor family targets personal, business, industrial and commercial embedded computing devices that require ultra low power consumption, rock solid reliability and compatibility with standard x86 operating systems and software applications.
VIA Eden processors are scalable from 400MHz to 1.5GHz all within a maximum thermal envelope of 7.5 watts, and are available with a diverse range of feature sets that enable PC functionality and connectivity from traditionally single function devices.
