The module consists of eight 16Mx8 DDR SDRAMs in 66 pin TSOP package 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 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.
