Size depends on complexity of the processor, on what is included (Chinese makers tends to have short datasheets which frequently skip useful information) and style of presentation. I recently feched Intel datasheet giving essentually the instruction set, it is more than 5000 pages. Several STM datasheet for relatively simple processors have more than 1000 pages. Some STM datasheets contain a lot of examples in C, that adds bulk. STM has general timer design which can be specialized to remove various features. Instead of describing general design and then specifying features of each timer they have separate section for each compbination of features present in a timer. This leads to significant duplication, where bulk of a section is the same as section for another timer, but some places differ. IIRC have a datasheet with about 5000 pages. 16000 pages would be reasonable if the processor contains a lot of features and they want to describe it in depth. Or could be just mistuned text-generator which is spitting text based on some templates and a database. -- Waldek Hebisch
