GUIDELINES FOR UPGRADING FROM THE ST92F120 (0.50 µm) TO THE ST92F124...

easier to address up to 4 external Mbytes. But segments 0h to 3h and 20h to 23h are not ex-

ternally available.

1.4.2 Flash Sector Organization

Sectors F0 to F3 have a new organization in the 128K and 60K Flash devices as shown in
