MB81P643287-50

The Fujitsu MB81P643287-50 is a CMOS Synchronous Dynamic Random Access Memory (SDRAM) with Fujitsu advanced FCRAM (Fast Cycle Random Access Memory) Core Technology, containing 67,108,864 memory cells accessible in an 32-bit format. The MB81P643287-50 features a fully synchronous operation referenced to clock edge whereby all operations are synchronized at a clock input which enables high performance and simple user interface coexistence. The MB81P643287-50 is designed to reduce the complexity of using a standard dynamic RAM (DRAM) which requires many control signal timin.g constraints. The MB81P643287-50 uses Double Data Rate (DDR) where data bandwidth is twice of fast speed compared with regular SDRAMs.

The MB81P643287-50 is ideally suited for Digital Visual Systems, High Performance Graphic Adapters, Hardware Accelerators, Buffers, and other applications where large memory density and high effective bandwidth are required and where a simple interface is needed.

The MB81P643287-50 adopts new I/O interface circuitry, SSTL_2 interface, which is capable of extremely fast data transfer of quality under either terminated or point to point bus environment.
