PRELIMINARY DATA SHEET  
256M bits DDR2 SDRAM  
EDE2504AASE (64M words × 4 bits)  
EDE2508AASE (32M words × 8 bits)  
EDE2516AASE (16M words × 16 bits)  
Features  
Description  
The EDE2504AA is a 256M bits DDR2 SDRAM  
1.8V power supply  
organized as 16,777,216 words × 4 bits × 4 banks.  
Double-data-rate architecture: two data transfers per  
clock cycle  
The EDE2508AA is a 256M bits DDR2 SDRAM  
organized as 8,388,608 words × 8 bits × 4 banks.  
Bi-directional, differential data strobe (DQS and  
/DQS) is transmitted/received with data, to be used in  
capturing data at the receiver  
They are packaged in 64-ball FBGA package.  
The EDE2516AA is a 256M bits DDR2 SDRAM  
organized as 4,194,304 words × 16 bits × 4 banks.  
DQS is edge aligned with data for READs: center-  
aligned with data for WRITEs  
It is packaged in 84-ball FBGA package.  
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  
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  
1.8V (SSTL_18 compatible) I/O  
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  
Programmable RDQS, /RDQS output for making × 8  
organization compatible to × 4 organization  
/DQS, (/RDQS) can be disabled for single-ended  
Data Strobe operation.  
FBGA package is lead free solder (Sn-Ag-Cu)
