Although iPods have many other components, here we are only listing the components that might be relavent to cracking firmware encryption. If you have any suggestions for any other components to add, just post on the talk page or IRC. Links to datasheets are important if they can be found. For a visual hardware reference, visit the [[Hardware annotation]] page.

'''The datasheet for the S5L8700X series (possibly part of it?) has been located!''' You can download it [http://rapidshare.com/files/101234522/S5L8700X-DS.pdf.html here] (link from [http://www.rockbox.org/twiki/bin/view/Main/SamsungSA58#SA58700_codename_Blues this Rockbox wiki page]), but I (cmwslw) will try to get it hosted on my site soon. The datasheet describes every pin (page 1-5) and instruction (page 3-1) in detail. We now know the exact locations of the JTAG pins, and a lot of other information about the chip.
