Application Scenarios & Design Considerations

4 Banks x 1M x 16Bit Synchronous DRAM

Alternative Part Number

  • IS42S16400J-7TL --: 64Mb SDR SDRAM in the same 54-pin TSOP-II package with comparable speed grade, widely available and pin-compatible replacement.
  • MT48LC4M16A2P-7E --: 64Mb SDR SDRAM organized 4M x 16, same package and interface, a well-established drop-in alternative for legacy designs.
  • W9864G6JH-6 --: 64Mb SDR SDRAM with matching 4M x 16 organization and TSOP-II footprint, suitable as a second-source option.
