PRELIMINARY DATA SHEET  
256M bits DDR Mobile RAM  
WTR (Wide Temperature Range)  
EDD2532DGBH-TT (8M words × 32 bits)  
Features  
Specifications  
Density: 256M bits  
Organization  
DLL is not implemented  
Low power consumption  
× 32 bits: 2M words × 32 bits × 4 banks  
Package: 90-ball FBGA  
Lead-free (RoHS compliant) and Halogen-free  
Power supply: VDD, VDDQ = 1.7V to 1.95V  
Data rate: 333Mbps/266Mbps (max.)  
2KB page size  
Double-data-rate architecture; two data transfers per  
one 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  
Row address: A0 to A11  
DQS  
Column address: A0 to A8  
Four internal banks for concurrent operation  
Interface: LVCMOS  
DQS is edge-aligned with data for READs; center-  
aligned with data for WRITEs  
Differential clock inputs (CK and /CK)  
Commands entered on each positive CK edge: data  
Burst lengths (BL): 2, 4, 8, 16  
Burst type (BT):  
Sequential (2, 4, 8, 16)  
Interleave (2, 4, 8, 16)  
/CAS Latency (CL): 3  
and data mask referenced to both edges of DQS  
Data mask (DM) for write data  
Burst termination by burst stop command and  
Precharge command  
Wide temperature range  
TA = 20°C to +85°C  
Precharge: auto precharge option for each burst  
access  
Driver strength: normal, 1/2, 1/4, 1/8  
Refresh: auto-refresh, self-refresh  
Refresh cycles: 4096 cycles/64ms  
Average refresh period: 15.6µs  
Operating ambient temperature range  
TA = 20°C to +85°C
