The module consists of eight 32Mx8 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 without notice. VCC = VCCQ = +2.6V ±0.1V (200MHz) JEDEC standard 184 pin DIMM package JD3 PCB height: 30.48 (1.20") max NOTE: Consult factory for availability of: Lead-free products Vendor source control option 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 ...
