The WV3EG216M64STSU is a 2x16Mx64 Double
Data Rate SDRAM memory module based on 256Mb
DDR SDRAM components. The module consists of
eight 16Mx16 DDR SDRAMs in 66 pin TSOP package
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 Lenths 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.
