HB56U272E-6B/7B/8B

2,097,152-Word × 72-Bit High Density Dynamic RAM Module

168-pin JEDEC Standard Outline Buffered 8BYTE DIMM

Rev.0.0

Feb.02,1996

Description

The HB56U272E 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 HB56U272E is a 2M x

72 dynamic RAM module, mounted 9 pieces of 16-Mbit DRAM (HM5117805BTT) sealed in TSOP

package and 2 pieces of 16-bit BiCMOS line driver (74ABT16244) sealed in TSOP package. The

HB56U272E offers Extended Data Out(EDO) Page Mode as a high speed access mode. An outline of the

HB56U272E is 168-pin socket type package (dual lead out). Therefore, the HB56U272E makes high

density mounting possible without surface mount technology. The HB56U272E provides common data

inputs and outputs. Decoupling capacitors are mounted beside each TSOP on the its module board.
