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. * This product is under development, is not qualified or characterized and is subject to change or cancellation without notice. 200 pin SO-DIMM package D4: 35.5mm (1.38") Package height options NOTE: Consult factory for availability of: RoHS compliant products Vendor source control options Industrial temperature option OPERATING FREQUENCIES DDR400@CL=3 Clock Speed CL-tRCD-tRP 200MHz 3-3-3 DDR333@CL=2.5 166MHz 2.5-3-3 DDR266@CL=2 133MHz 2-2-2 DDR266@CL=2.5 133MHz 2.5...
