PRELIMINARY DATA SHEET  
8GB Registered DDR2 SDRAM DIMM  
EBE82AF4A1RA (1024M words × 72 bits, 4 Ranks)  
Specifications  
Features  
Density: 8GB  
Organization  
1024M words × 72 bits, 4 ranks  
Mounting 36 pieces of 2G bits DDR2 SDRAM with  
DDP (FBGA)  
Double-data-rate architecture; two data transfers per  
clock cycle  
The high-speed data transfer is realized by the 4 bits  
prefetch pipelined architecture  
Bi-directional differential data strobe (DQS and /DQS)  
is transmitted/received with data for capturing data at  
the receiver  
DDP: 2 pieces of 1Gb chips sealed in one package  
Package: 240-pin socket type dual in line memory  
module (DIMM)  
DQS is edge-aligned with data for READs; center-  
aligned with data for WRITEs  
PCB height: 30.0mm  
Lead pitch: 1.0mm  
Lead-free (RoHS compliant)  
Power supply: VDD = 1.8V 0.1V  
Data rate: 667Mbps/533Mbps (max.)  
Differential clock inputs (CK and /CK)  
DLL aligns DQ and DQS transitions with CK  
transitions  
Commands entered on each positive CK edge; data  
referenced to both edges of DQS  
Posted /CAS by programmable additive latency for  
better command and data bus efficiency  
Eight internal banks for concurrent operation  
(components)  
Off-Chip-Driver Impedance Adjustment and On-Die-  
Interface: SSTL_18  
Burst lengths (BL): 4, 8  
/CAS Latency (CL): 3, 4, 5  
Precharge: auto precharge option for each burst  
access  
Termination for better signal quality  
/DQS can be disabled for single-ended Data Strobe  
operation  
1 piece of PLL clock driver, 2 pieces of register driver  
and 1 piece of serial EEPROM (2K bits EEPROM) for  
Presence Detect (PD)  
Refresh: auto-refresh, self-refresh  
Refresh cycles: 8192 cycles/64ms  
Average refresh period  
7.8μs at 0°C TC ≤ +85°C  
3.9μs at +85°C < TC ≤ +95°C  
Operating case temperature range  
TC = 0°C to +95°C
