DESCRIPTION
The WV3EG232M64STSU is a 2x32Mx64 Double Data Rate SDRAM memory module based on 512Mb DDR SDRAM component. The module consists of eight 32Mx16 DDR SDRAMs in 66 pin TSOP packages mounted on a 200 pin FR4 substrate. Synchronous design allows precise cycle control with the use of system clock. Data 1/0 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.
OPERATING FREQUENCIES
DDR333@CL=2.5 Clock Speed CL-tRCD-tRP 166MHz 2.5-3-3
