EDI7F33512C
512Kx32 Flash
DESCRIPTION
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 microprocessors without wait states.
