You can confirm this information and more details in Component Marking Information section, on pages 16 and 17 of the Intel Atom(R) Processor E3800 Specification Update document # 329901 that can be found at the following website:

This document is accessible when you are logged into your Resource Design Center (RDC) privileged account at:
