A datasheet is a document summarizing the performance and other characteristics of a component (e.g. an electronic component), a sub-system (e.g. a power supply) or software in enough detail to be used by a design engineer to design the component into a system. Typically a datasheet was created by system manufacturer and begins with an introductory page describing the rest of the document, followed by listings of specific components, with further information on the connectivity of the devices. In cases where there is relevant source code to include, it is usually attached near the end of the document or separated into another file.

Terrific work! This is the type of information that should be shared around the web. Shame on the search engines for not positioning this post higher!
Good list , very helpfull
Nice post and this post helped me alot in my college assignement. Thanks you on your information.
