Description
The HB52F168GB and HB52D168GB are a 16M × 64 × 1 banks Synchronous Dynamic RAM Micro Dual In-line Memory Module (Micro DIMM), mounted 4 pieces of 256-Mbit SDRAM (HM5225165BTT) sealed in TSOP package and 1 piece of serial EEPROM (2-kbit EEPROM) for Presence Detect (PD). An outline of the products is 144-pin Zig Zag Dual tabs socket type compact and thin package. Therefore, they make high density mounting possible without surface mount technology. They provide common data inputs and outputs. Decoupling capacitors are mounted beside TSOP on the module board.
