EBE21RD4AEFA - 2GB Registered DDR2 SDRAM DIMM

Description

The EBE21RD4AEFA is a 256M words × 72 bits, 2 ranks DDR2 SDRAM Module, mounting 36 pieces of 512M bits DDR2 SDRAM sealed in FBGA (µBGA) package.

Read and write operations are performed at the cross points of the CK and the /CK.

Features

  • 240-pin socket type dual in line memory module (DIMM)  PCB height: 30.0mm  Lead pitch: 1.0mm  Lead-free.
  • Power supply: VDD, VDDQ = 1.8V ± 0.1V.
  • Data rate: 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 READ.

DATA SHEET www.DataSheet4U.com 2GB Registered DDR2 SDRAM DIMM EBE21RD4AEFA (256M words × 72 bits, 2 Ranks) Description The EBE21RD4AEFA is a 256M words × 72 bits, 2 ranks DDR2 SDRAM Module, mounting 36 pieces of 512M bits DDR2 SDRAM sealed in FBGA (µBGA) package. Read and write operations are performed at the cross points of the CK and the /CK. This highspeed data transfer is realized by the 4bits prefetchpipelined 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.
