DATA SHEET  
1GB Unbuffered DDR2 SDRAM DIMM  
EBE11ED8ABFA (128M words × 72 bits, 2 Ranks)  
Description  
Features  
The EBE11ED8ABFA is 128M words × 72 bits, 2 ranks  
DDR2 SDRAM unbuffered module, mounting 18 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  
register, the on-chip Delay Locked Loop (DLL) can be  
set enable or disable. This module provides high  
density mounting without utilizing surface mount  
240-pin socket type dual in line memory module  
(DIMM)  
PCB height: 30.0mm  
Lead pitch: 1.0mm  
Lead-free  
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  
technology.  
Decoupling capacitors are mounted  
beside each FBGA (µBGA) on the module board.  
DQS is edge aligned with data for READs: center-  
aligned with data for WRITEs  
Note: Do not push the components or drop the  
modules in order to avoid mechanical defects,  
which may result in electrical defects.  
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  
(Component)  
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
