White Electronic Designs WV3EG264M64EFSU-D4 PRELIMINARY* 1GB – 2x64Mx64 DDR SDRAM UNBUFFERED FEATURES PC2700 @ CL2.5 Double-data-rate architecture 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) Auto and self refresh, (8K/64ms refresh) Serial presence detect Power supply: VCC/VCCQ: 2.5V ± 0.2V Dual Rank Standard 200 pin SO-DIMM package Package height options: D4: 31.75 mm (1.25”) NOTE: Consult factory for availability of: RoHS compliant products Vendor source control options Industrial temperature option * This product is under development, is not qualied or characterized and is subject to change without notice. DESCRIPTION The WV3EG264M64EFSU is a 2x64Mx64 Double Data Rate SDRAM memory module based on 512Mb DDR SDRAM component. The module consists of sixteen 64Mx8 bit with 4 banks DDR SDRAMs in FBGA packages mounted on a 200 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.
