Hi. Recently, I have been interested in hardware mods for the 84 Plus SE. Do we have any documentation of the different pinouts of the ASICs?
Thanks. :)

I've never seen one. I know critor made a few for the Nspire back when they were trying to hardware hack it, but I've never seen any for the 84+.
I could be entirely wrong of course ;D The specific people I could see having one would be critor, drDnar, and kerm, with kerm being the most likely. Hopefully though, someone will post a pinout for you, but the chip itself has no official documentation.

As the term Application-Specific implies, the chip is only manufactured for TI's graphing calculators. They don't publish a data sheet. Kerm is the best bet for that kind of information. I may, in the next few weeks, be able to provide micrographs of the ASIC, but that's a long way from a pinout.
The TI-84+ and the TI-84+SE appear to use exactly the same ASIC; only the actual flash chip differs. Be aware that there are at least three known revisions of the ASIC, whose pinouts may all be quite different.

I guess I'll get my oscilloscope...
