Description

The HB56A172E belongs to 8 Byte DIMM (Dual In-line Memory Module) family, and has been developed as an optimized main memory solution for 4 and 8 Byte processor applications.

The HB56A172E is a 1 M × 72 ECC mode dynamic RAM module, mounted 18 pieces of 4 Mbit DRAM(HM514400CTT) sealed in TSOP package and 2 pieces of 16 bit BiCMOS line driver (74ABT16244) sealed in TSSOP package. An outline of the product  is 168-pin socket type package (dual lead out).

Therefore, the HB56A172E makes high density mounting possible without surface mount technology. It provides common data inputs and outputs. Decoupling capacitors are mounted beside the each TSOP on the module board.
