×
32 dynamic RAM Small Outline Dual In-line Memory Module (S.O.DIMM),
mounted 8 pieces of 16-Mbit DRAM (HM51W17400) sealed in TSOP package. An outline of the
HB56TW432D, HB56TW433D is 72-pin Zig Zag Dual tabs socket type compact and thin package.
Therefore, the HB56TW432D, HB56TW433D make high density mounting possible without surface mount
technology. The HB56TW432D, HB56TW433D provide common data inputs and outputs. Decoupling
capacitors are mounted on the module board.
