HB56TW433D Series

4,194,304-word × 32-bit High Density Dynamic RAM Module

ADE-203-

Rev. 0.0

Dec. 1, 1995

Description

The HB56TW433D is a 4 M × 32 dynamic RAM Small Outline DIMM (S. O. DIMM), mounted 8 pieces of

16Mbit DRAM (HM51W17400BTS/ BLTS) sealed in TSOP package. An outline of the HB56TW433D is

72-pin Zig Zag Dual tabs socket type compact and thin package. Therefore, the HB56TW433D makes high

density mounting possible without surface mount technology. Decoupling capacitors are mounted beside the

each TSOP of its module board.
