DESCRIPTION
The WV3EG216M64STSU is a 2x16Mx64 Double Data Rate SDRAM memory module based on 256Mb DDR SDRAM ponents. 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.
