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.
