White Electronic Designs WV3EG265M64EFSU-D4 1GB – 2x64Mx64 DDR SDRAM UNBUFFERED, w/PLL FEATURES Double-data-rate architecture PC2700 and PC2100 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 with EEPROM Power supply: VCC/VCCQ: 2.5V ± 0.2V Dual Rank 200 pin SO-DIMM package Package height options: D4: 31.75 mm (1.25”) * This product is subject to change without notice. DESCRIPTION The WV3EG265M64EFSU 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 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.
