PRELIMINARY DATA SHEET  
512MB Registered DDR SDRAM DIMM  
EBD52RC8AKFA (64M words × 72 bits, 2 Ranks)  
Description  
Features  
The EBD52RC8AKFA is a 64M words × 72 bits, 2  
ranks Double Data Rate (DDR) SDRAM Module,  
mounting 18 pieces of DDR SDRAM sealed in TSOP  
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 2-bit prefetch-  
pipelined architecture. Data strobe (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 technology. Decoupling  
capacitors are mounted beside each TSOP on the  
module board.  
184-pin socket type dual in line memory module  
(DIMM)  
PCB height: 30.48mm  
Lead pitch: 1.27mm  
2.5V power supply  
Data rate: 333Mbps (max.)  
2.5 V (SSTL_2 compatible) I/O  
Double Data Rate architecture; two data transfers per  
clock cycle  
Bi-directional, data strobe (DQS) is transmitted  
/received with data, to be used in capturing data at  
the receiver  
Data inputs and outputs are synchronized with DQS  
4 internal banks for concurrent operation  
(Component)  
DQS is edge aligned with data for READs; center  
aligned with data for WRITEs  
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  
Data mask (DM) for write data  
Auto precharge option for each burst access  
Programmable burst length: 2, 4, 8  
Programmable /CAS latency (CL): 2, 2.5  
Refresh cycles: (8192 refresh cycles /64ms)  
7.8µs maximum average periodic refresh interval  
2 variations of refresh  
Auto refresh  
Self refresh  
1 piece of PLL clock driver, 1 piece of register driver  
and 1 piece of serial EEPROM (2k bits EEPROM) for  
Presence Detect (PD)
