The datasheet for the S5L8700X series can be downloaded here, but I (cmwslw) will try to get it hosted on my site soon. It matches the official Samsung 8700 info page. The datasheet describes every pin (page 1-5) and instruction (page 3-1) of the 8700 series in detail.
Package differences
The pin locations described in the datasheet are not the actual locations for the iPod's 226-pin FBGA version. This forum thread describes the pinout of another S5L8700 package in another device (see right for ball layout).
Possible uses
If we could use the datasheet to find a way of reading the 50KB embedded ROM, we would be able to figure out how the firmware is decrypted. Ironically though, if we could run custom code, we wouldn't neet to read the boot ROM in the first place. So as of now, we have no real use for the datasheet.
