Looks like a key card (early version) to me.

The only data on that chip will be the code necessary to unlock whatever that circuit board plugged into.

Hey LoLa, Welcome to EP!

The "clear dot" with 40 traces coming out of it is almost certainly some kind of embedded processor or PGA (Programable Gate Array) but without instructions, protocols or clues on how to interface with it, there is not much hope of gleaning anything useful from the Atmel FLASH ... It certainly looks like a "demo board", so it is possible it could be an early key card, it is also possible the "Clear Dot" is what is being "Demonstrated", and that the ATMEL Flash is simply there to store code and/or Data.

Hope it helps!

Fish
