1Megx32 Flash Module
The EDI7F34IMC and EDI7F2341MC are orga-
nized as one and two banks of 1 Meg x 32 respec-
tively. The modules are based on Sharp's
LH28F800SU - 1Megx8 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 micro-
processors without wait states.
