1Mx32 FLASH MODULE
DESCRIPTION
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.
