The EDI7F331MC and EDI7F2331MC are organized as one
and two banks of 1Mx32 respectively. The modules are based
on AMDs AM29F080 - 1Mx8 Flash device in TSOP packages
which are mounted on an FR4 substrate.
Both modules offer access times between 80 and 150ns
allowing for operation of high-speed microprocessors without
wait states.
