Description
The HB52F328DC is a 16M × 64 × 2 banks Synchronous Dynamic RAM Small Outline Dual In-line Memory
Module (S.O.DIMM), mounted 8 pieces of 256-Mbit SDRAM (HM5225165BTT) sealed in TSOP package
and 1 piece of serial EEPROM (2-kbit) for Presence Detect (PD). An outline of the product is 144-pin Zig
Zag Dual tabs socket type compact and thin package. Therefore, it makes high density mounting possible
without surface mount technology. It provides common data inputs and outputs. Decoupling capacitors are
mounted beside TSOP on the module board.
