DATA SHEET

512MB Unbuffered SDRAM DIMM

EBS52UC8APFA (64M words × 64 bits, 2 banks)

Description

The EBS52UC8APFA is 64M words × 64 bits, 2 banks

Synchronous Dynamic RAM Registered Module,

mounted 16 pieces of 256M bits SDRAM sealed in

TSOP 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.
