DATA SHEET
512MB SDRAM S.O.DIMM
EBS52UC8APSA (64M words × 64 bits, 2 bank)
Description
The EBS52UC8APSA is 64M words × 64 bits, 2 banks
Synchronous Dynamic RAM Small Outline Dual In-line
Memory Module (S.O.DIMM), mounted 16 pieces of
256M bits SDRAM sealed in µBGA^ package. This
module provides high density and large quantities of
memory in a small space without utilizing the surface
mounting technology. Decoupling capacitors are
mounted on power supply line for noise reduction.
Note : Do not push the cover or drop the modules in
order to protect from mechanical defects, which
would be electrical defects.
