Revision 1.0
EDC4BV7282B-60(J/T)G-S
32MByte (4M x 72) CMOS
EDO DRAM Module - 3.3V (ECC), Buffered
General Description
The EDC4BV7282B-60(J/T)G-S is a high performance, EDO (Extended Data Out) 32-megabyte dynamic RAM module organized
as 4M words by 72 bits, in a 168-pins, dual-in-line (DIMM) memory module with ECC.
The module utilizes eighteen, Fujitsu MB81V17805B-60(PJ/FN) CMOS 2Mx8 EDO dynamic RAMs in a surface mount package
on an epoxy laminate substrate. Each device is accompanied by a decoupling capacitor for improved noise immunity.
Control lines provided are such that Dword control is possible. All signals are buffered (74ABT16244 or equivalent) except RAS,
data, and IDs.
