Description
The HB56UW873E belongs to 8 Byte DIMM (Dual In-line Memory Module) family, and has been developed
as an optimized main memory solution for 4 and 8 Byte processor applications. The HB56UW873E is a 8M
× 72 dynamic RAM module, mounted 9 pieces of 64-Mbit DRAM (HM5165805) sealed in TSOP package and
2 pieces of 16-bit line driver sealed in TSSOP package. The HB56UW873E offers Extended Data Out (EDO)
Page Mode as a high speed access mode. An outline of the HB56UW873E is 168-pin socket type package (dual
lead out). Therefore, the HB56UW873E makes high density mounting possible without surface mount
technology. The HB56UW873E provides common data inputs and outputs. Decoupling capacitors are
mounted beside each TSOP on the its module board.
