32-bit High Density Dynamic RAM Module
ADE-203-728A (Z)
Rev.1.0
Feb. 20, 1997
Description
The HB56A832BS/SBS is a 8M
×
32 dynamic RAM module, mounted 16 pieces of 16-Mbit DRAM
(HM5117400) sealed in SOJ package. The HB56A432BR/SBR is a 4M
×
32 dynamic RAM module,
mounted 8 pieces of 16-Mbit DRAM (HM5117400) sealed in SOJ package. An outline of the
HB56A832BS/SBS, HB56A432BR/SBR is 72-pin single in-line package.
Therefore, the
HB56A832BS/SBS, HB56A432BR/SBR make high density mounting possible without surface mount
technology. The HB56A832BS/SBS, HB56A432BR/SBR provide common data inputs and outputs.
Decoupling capacitors are mounted on the module board.
