×
32-bit High Density Dynamic RAM Module
Description
The HB56U232 is a 2 M
×
32 dynamic RAM module, mounted 16 pieces of 4-Mbit DRAM (HM514405CS)
sealed in SOJ package.
An outline of the HB56U232 is 72-pin single in-line package. Therefore, the HB56U232 makes high density
mounting possible without surface mount technology. The HB56U232 provides common data inputs and
outputs. Decoupling capacitors are mounted beneath each SOJ on the module board.
The HB56U232 offers Extended Data Out (EDO) page mode as a high speed access mode.
