Application Scenarios & Design Considerations

4 Banks x 2M x 16bits Synchronous DRAM

Alternative Part Number

  • IS42S16800F-7TL --: Pin-compatible 128Mb SDR SDRAM in the same 54-pin TSOP-II package with comparable speed grade, widely available and a common drop-in replacement.
  • MT48LC8M16A2P-7E --: 128Mb SDR SDRAM organized 8M x 16 in 54-pin TSOP-II, functionally equivalent timing and interface, from a major memory vendor.
  • W9825G6KH-6 --: 256Mb SDR SDRAM in 54-pin TSOP-II with compatible pinout and interface; higher density but usable as a substitute where board routing allows.
