80 Pin SIMM (JEDEC)

The EDI7F331MV and EDI7F2331MV are organized as one and

two banks of 1Mx32 respectively. The modules are based onAMDs

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.
