Description
The HB52D88GB is a 8M × 64 × 1 banks Synchronous Dynamic RAM Micro Dual In-line Memory Module
(Micro DIMM), mounted 4 pieces of 128-Mbit SDRAM (HM5212165FTD) sealed in TSOP package and 1
piece of serial EEPROM (2-kbit EEPROM) 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.
