 Package
 80 Pin SIMM (JEDEC)
The EDI7F331MV and EDI7F2331MV are organized as one and
two banks of 1Mx32 respectively. The modules are based on
AMDs AM29LV008T - 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.
