Description
The HB56UW3272ETK belongs to 8-byte DIMM (Dual in-line Memory Module) family , and has been
developed an optimized main memory solution for 4 and 8-byte processor applications. The
HB56UW3272ETK is 32 M
×
72 Dynamic RAM Module, mounted 36 pieces of 64-Mbit DRAM
(HM5165405) sealed in TSOP package and 2 pieces of 16-bit line driver sealed in TSSOP package. The
HB56UW3272ETK offers Extended Data Out (EDO) Page Mode as a high speed access mode. An outline
of the HB56UW3272ETK is 168-pin socket type package (dual lead out). Therefore, the
HB56UW3272ETK makes high density mounting possible without surface mount technology. The
HB56UW3272ETK provides common data inputs and outputs. Decoupling capacitors are mounted beside
each TSOP on the module board.
