Description

The HB56R864ES 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. It is a 8M × 64 dynamic RAM module, mounted 32 pieces of 16-Mbit DRAM (HM5116400) sealed in TCP package, 1 piece of 16-bit BiCMOS line driver (74ABT16244) sealed in TSSOP package and 1 piece of 20-bit BiCMOS line driver (74ABT16827) sealed in TSSOP package. An outline of the HB56R864ES is 168-pin socket type package (dual lead out). Therefore, it makes high density mounting possible without surface mount technology. It provides common data inputs and outputs. Decoupling capacitors are mounted beside each TSOP on the module board.
