Description
The HB52RF649DC, HB52RD649DC are a 64M
×
72
×
2 banks Synchronous Dynamic RAM Small Outline
Dual In-line Memory Module (S.O.DIMM), mounted 18
pieces of 256M bits SDRAM sealed in TCP package
and 1 piece of serial EEPROM (2k bits) 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 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.
