Description
The HB56UW1673E belongs to 8-byte DIMM (Dual in-line Memory Module) family , and have been
developed an optimized main memory solution for 4 and 8-byte processor applications. The
HB56UW1673E is a 16 M
×
72 Dynamic RAM Module, mounted 18 pieces of 64-Mbit DRAM
(HM5165405) sealed in TSOP package and 2 pieces of 16-bit line driver sealed in TSSOP package. The
HB56UW1673E offers Extended Data Out (EDO) Page Mode as a high speed access mode. An outline of
the HB56UW1673E is 168-pin socket type package (dual lead out). Therefore, the HB56UW1673E makes
high density mounting possible without surface mount technology. The HB56UW1673E provides common
data inputs and outputs. Decoupling capacitors are mounted beside each TSOP on the its module board.
