UNLESS OTHERWISE AGREED IN WRITING BY INTEL, THE INTEL PRODUCTS ARE NOT DESIGNED NOR INTENDED FOR ANY

APPLICATION IN WHICH THE FAILURE OF THE INTEL PRODUCT COULD CREATE A SITUATION WHERE PERSONAL INJURY OR

Intel may make changes to specifications and product descriptions at any time, without notice. Designers must not rely on the

absence or characteristics of any features or instructions marked “reserved” or “undefined.” Intel reserves these for future

definition and shall have no responsibility whatsoever for conflicts or incompatibilities arising from future changes to them. The

information here is subject to change without notice. Do not finalize a design with this information.

Intel® Atom™ Processor N500 series may contain design defects or errors known as errata which may cause the product to

deviate from published specifications. Current characterized errata are available on request.

Intel processor numbers are not a measure of performance. Processor numbers differentiate features within each processor

family, not across different processor families. Over time processor numbers will increment based on changes in clock, speed,

cache, FSB, or other features, and increments are not intended to represent proportional or quantitative increases in any

particular feature. Current roadmap processor number progression is not necessarily representative of future roadmaps.

See www.intel.com/products/processor_number for details.
