EBE51RD8AGFA 512MB Registered DDR2 SDRAM DIMM

EBE51RD8AGFA 512MB Registered DDR2 SDRAM DIMM

The EBE51RD8AGFA is a 64M words × 72 bits, 1 rank DDR2 SDRAM Module, mounting 9 pieces of DDR2 SDRAM sealed in FBGA (µBGA) 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 4bits prefetch-pipelined architectu.

Features

• 240-pin socket type dual in line memory module (DIMM)  PCB height: 30.0mm  Lead pitch: 1.0mm  Lead-free (RoHS compliant)
• Power supply: VDD = 1.8V ± 0.1V
• Data rate: 667Mbps/533Mbps/400Mbps (max.)
• SSTL_18 compatible I/O
• Double-data-rate architecture: two data transfers per clock cycle
• Bi-directional, data strobe (DQS and /DQS) is transmitted /received with data, to be used in capturing data at the receiver
• 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
