PRELIMINARY DATA SHEET

512MB Unbuffered DDR2 SDRAM DIMM

EBE51ED8ABFA

(64M words

72 bits, 1 Rank)

Description

The EBE51ED8ABFA is 64M words

72 bits, 1 rank

DDR2 SDRAM unbuffered module, mounting 9 pieces

of 512M bits DDR2 SDRAM sealed in FBGA (µBGA



)

package. Read and write operations are performed at

the cross points of the CK and the /CK. This high-

speed data transfer is realized by the 4 bits prefetch-

pipelined architecture. Data strobe (DQS and /DQS)

both for read and write are available for high speed and

reliable data bus design. By setting extended mode

set enable or disable. This module provides high

density mounting without utilizing surface mount

technology.

Decoupling capacitors are mounted

beside each FBGA (µBGA) on the module board.

Note: Do not push the components or drop the

modules in order to avoid mechanical defects,

which may result in electrical defects.

Features

•

240-pin socket type dual in line memory module

(DIMM)



PCB height: 30.0mm



Lead pitch: 1.0mm

•

1.8V power supply

•

Data rate: 533Mbps/400Mbps (max.)

•

1.8V (SSTL_18 compatible) I/O

•

Double-data-rate architecture: two data transfers per

clock cycle

•

Bi-directional, differential data strobe (DQS and

/DQS) is transmitted/received with data, to be used in

capturing data at the receiver

•

DQS is edge aligned with data for READs: center-

aligned with data for WRITEs

•

Differential clock inputs (CK and /CK)

•

DLL aligns DQ and DQS transitions with CK

transitions

•

Commands entered on each positive CK edge: data

and data mask referenced to both edges of DQS

•

Four internal banks for concurrent operation

(components)

•

Data mask (DM) for write data

•

Burst lengths: 4, 8

•

/CAS Latency (CL): 3, 4, 5

•

Auto precharge operation for each burst access

•

Auto refresh and self refresh modes

•

7.8µs average periodic refresh interval

•

Posted CAS by programmable additive latency for

better command and data bus efficiency

•

Off-Chip-Driver Impedance Adjustment and On-Die-

Termination for better signal quality

•

/DQS can be disabled for single-ended Data Strobe

operation
