36-bit High Density Dynamic RAM Module
ADE-203-729A (Z)
Rev.1.0
Feb. 20, 1997
Description
The HB56D836BR/SBR is a 8M
×
36 dynamic RAM module, mounted 16 pieces of 16-Mbit DRAM
(HM5117400) sealed in SOJ package and 8 pieces of 4-Mbit DRAM (HM514100) sealed in SOJ package.
The HB56D436BR/SBR is a 4M
×
36 dynamic RAM module, mounted 8 pieces of 16-Mbit DRAM
(HM5117400) sealed in SOJ package and 4 pieces of 4-Mbit DRAM (HM514100) sealed in SOJ package.
An outline of the HB56D836BR/SBR, HB56D436BR/SBR is 72-pin single in-line package. Therefore, the
HB56D836BR/SBR, HB56D436BR/SBR make high density mounting possible without surface mount
technology. The HB56D836BR/SBR, HB56D436BR/SBR provide common data inputs and outputs.
Decoupling capacitors are mounted on the module board.
