Description

The HB56A840BR is a 8M ×40 dynamic RAM module, mounted 20 pieces of 16-Mbit DRAM (HM5116400) sealed in SOJ package. The HB56A440BR is a 4M × 40 dynamic RAM module, mounted 10 pieces of 16-Mbit DRAM (HM5116400) sealed in SOJ package. An outline of the HB56A840BR, HB56A440BR is 72-pin single in-line package. Therefore, they make high density mounting possible without surface mount technology. They provide common data inputs and outputs. Decoupling capacitors are mounted on the module board.
