EBE25RC8AAFA - 256MB Registered DDR2 SDRAM DIMM

Description

The EBE25RC8AAFA is a 32M words × 72 bits, 1 rank DDR2 SDRAM Module, mounting 9 pieces of DDR2 SDRAM sealed in FBGA 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 architecture.

Features

  • 240-pin socket type dual in line memory module (DIMM)  PCB height: 30.0mm  Lead pitch: 1.0mm  Lead-free.
  • 1.8V power supply.
  • Data rate: 533Mbps/400Mbps (max. ).
  • 1.8 V (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 al.

PRELIMINARY DATA SHEET www.DataSheet4U.com 256MB Registered DDR2 SDRAM DIMM EBE25RC8AAFA (32M words × 72 bits, 1 Rank) Description The EBE25RC8AAFA is a 32M words × 72 bits, 1 rank DDR2 SDRAM Module, mounting 9 pieces of DDR2 SDRAM sealed in FBGA 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 architecture. Data strobe (DQS and /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 FBGA on the module board.
