DESCRIPTION The WV3EG64M72ETSU is a 64Mx72 Double Data Rate SDRAM memory module based on 512Mb DDR SDRAM components. The module consists of nine 64Mx8 DDR SDRAMs in 66 pin TSOP packages mounted on a 184 pin substrate. Synchronous design allows precise cycle control with the use of system clock. Data I/O transactions are possible on both edges and Burst Lengths allow the same device to be useful for a variety of high bandwidth, high performance memory system applications. www.DataSheet4U.com OPERATING FREQUENCIES DDR333 @CL=2.5 Clock Speed CL-tRCD-tRP 166MHz 2.5-3-3 October 2005 Rev. 0 1 White Electronic Designs Corporation (602) 437-1520 www.wedc.com White Electronic ...
