Hello Craig

What I am missing in your list is number of portpins

also I would like an comparison of the bigger ones

like 535, 537, dallas or other in PLCC 68 ...

standart 52 very often has not enough portpins.

A possibility for users to send commends about the specific chip
and bring in more info than in the datasheet

thank you for a good idea of that database
