ETC HB56A240BR-7CL

HB56A240BR Series
2,097,152-word × 40-bit High Density Dynamic RAM Module
ADE-203Rev. 0.0
Dec. 1, 1995
Description
The HB56A240BR is a 2M × 40 dynamic RAM module, mounted 20 pieces of 4-Mbit DRAM
(HM514400CS/CLS) sealed in SOJ package. An outline of the HB56A240BR is 72-pin single in-line
package. Therefore, the HB56A240BR makes high density mounting possible without surface mount
technology. The HB56A240BR provides common data inputs and outputs.
Its module board has decoupling capacitors beneath the each SOJ but only on the one side of its module
board.
