The HB52RD168GB is a 16M x 64 x 1 bank Synchronous Dynamic RAM Micro Dual In-line Memory Module (Micro DIMM), mounted 16 pieces of 64-Mbit SDRAM (HM5264405FTB) sealed in TCP package and 1 piece of ser ia l EEP RO M (2- kbit EEP RO M) for P rese nce De te ct (P D). An outline of the produc t is 144-pin Zig Za g Dua l tabs socke t type compa ct and thin pac kage . The ref ore, it make s high density mounting possible without surf ace mount tec hnology. It provide s common data inputs and outputs. De coupling ca pac itor s ar e mounted beside TCP on the module board. Note: Do not push the cover or drop the modules in order to protect from mechanical defects, which would be electrical defects.
