1GB – 2x64Mx64 DDR SDRAM UNBUFFERED w/PLL
FEATURES
DESCRIPTION
Double-data-rate architecture
Bi-directional data strobes (DQS)
Differential clock inputs (CK & CK#)
Programmable Read Latency 2,2.5 (clock)
The W3EG64128S is a 2x64Mx64 Double Data Rate
SDRAM memory module based on 512Mb DDR SDRAM
component. The module consists of eight 128Mx8 stack
DDR SDRAMs in 66 pin TSOP packages mounted on a
200 pin FR4 substrate.
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: 2.5V ± 0.2V
JEDEC standard 200 pin SO-DIMM package
•
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 without notice.
Package height options:
BD4: 31.75 mm (1.25”)
NOTE: Consult factory for availability of:
• RoHS compliant products
• Vendor source control options
• Industrial temperature option
