I am in the process of selecting a 2Mbyte*8 Data Flash for a project and am extremely surprised. I can get no 'real' answers from the suppliers, so I am coming to you.

Some chips list chip erase max time in the order of 30 seconds and some others list less than a second.

Since it seems to be utterly impossible to obtain anything but "typical" values, has anyone any knowledge whather this dramatic difference is marketing or technical.
