DATA SHEET  
256M bits DDR SDRAM  
EDD2508AETA (32M words × 8 bits)  
EDD2516AETA (16M words × 16 bits)  
Features  
Specifications  
Density: 256M bits  
Organization  
8M words × 8 bits × 4 banks (EDD2508AETA)  
4M words × 16 bits × 4 banks (EDD2516AETA)  
Package: 66-pin plastic TSOP (II)  
Lead-free (RoHS compliant)  
Power supply:  
Double-data-rate architecture; two data transfers per  
clock cycle  
The high-speed data transfer is realized by the 2 bits  
prefetch pipelined architecture  
Bi-directional data strobe (DQS) is transmitted  
/received with data for capturing data at the receiver  
Data inputs, outputs, and DM are synchronized with  
DQS  
DDR400:  
VDD, VDDQ = 2.6V ± 0.1V  
DQS is edge-aligned with data for READs; center-  
aligned with data for WRITEs  
DDR333, 266: VDD, VDDQ = 2.5V ± 0.2V  
Data rate: 400Mbps/333Mbps/266Mbps (max.)  
Four internal banks for concurrent operation  
Interface: SSTL_2  
Burst lengths (BL): 2, 4, 8  
Burst type (BT):  
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  
Data mask (DM) for write data  
Sequential (2, 4, 8)  
Interleave (2, 4, 8)  
/CAS Latency (CL): 2, 2.5, 3  
Precharge: auto precharge option for each burst  
access  
Driver strength: normal/weak  
Refresh: auto-refresh, self-refresh  
Refresh cycles: 8192 cycles/64ms  
Average refresh period: 7.8µs  
Operating ambient temperature range  
TA = 0°C to +70°C
