DESCRIPTION
The W3EG64128S is a 2x64Mx64 Double Data Rate
SDRAM memory module based on 512Mb DDR SDRAM
component. The module consists of sixteen 64Mx8 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.
NOTE: Consult factory for availability of:
• RoHS compliant products
• Vendor source control options
