Two days ago VIA had announced the OpenBook UMPC reference design
and today they are now announcing a new series of processors that is based upon their Isaiah architecture. The VIA Nano will be running up against Intel's recently announced Atom processors.
The VIA Nano processor series are 64-bit and operate between 1.0GHz and 1.8GHz. All of the Nano CPUs are built on a 65nm process and their idle power ranges from 100 to 500 mW. The Nano processors do ship with VIA's PadLock Security Engine for dual quantum random number generators, an AES Encryption Engine, NX bit, and SHA-1 and SHA-256 hashing.
