White Electronic Designs W3EG6462S-D3 -JD3 ADVANCED* 512MB – 2x32Mx64 DDR SDRAM UNBUFFERED FEATURES Double-data-rate architecture DDR200, DDR266, DDR333 and DDR400 JEDEC design specified Bi-directional data strobes (DQS) Differential clock inputs (CK & CK#) Programmable Read Latency 2,2.5 (clock) Programmable Burst Length (2,4,8) Programmable Burst type (sequential & interleave) Edge aligned data output, center aligned data input. Auto and self refresh Serial presence detect Dual Rank Power supply: www.DataSheet4U.com DESCRIPTION The W3EG6462S is a 2x32Mx64 Double Data Rate SDRAM memory module based on 256Mb DDR SDRAM components. The module consists of sixteen 32Mx8 DDR SDRAMs in 66 pin TSOP packages mounted on a 184 pin FR4 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. * This product is under development, is not qualified or characterized and is subject to change or cancellation without notice.
