AM9716 Eprom

[MHz]

Hi,
recently I got AMD AM9716 Eprom. The marking is strange, I have 2716 and 4716, but 9716 is new to me. In what whay this version differs from other?
Thank you for any information.

I believe 97xx and 27xx are the same thing.
97xx is an old designation of 27xx.
At least in datasheets there is no difference.

Ok, thanks a lot.

The 97xx parts were usually used to note a device that was made, but not necessarily screened, to military standards.


AMD did this to show their parts were a bit 'better' then the competition.

In the case of the 8080, AMD had a 9080, they referred to the 8080A as 'commodity' and the 9080A as 'standard', It was suppose to be a bit better then the commodity, and likely the price reflected that

I see. I there are not many around. I have never seen this marking in eprom chip before.
