512Kx32 Flash
The EDI7F33512, EDI7F233512 and EDI7F433512
are organized as 512Kx32 and 2x512Kx32 and
4x512Kx32 respectively. The modules are based on
AMD's AM29F040 - 512Kx8 Flash Device in TSOP
packages which are mounted on an FR4 substrate.
The modules offer access times between 80 and
150ns allowing for operation of high-speed micro-
processors without wait states.
