Application Scenarios & Design Considerations

16Meg x 8, 8Meg x16 & 4Meg x 32 128-MBIT SYNCHRONOUS DRAM

Alternative Part Number

  • MT48LC4M32B2P-7IT:G --: Same 128Mb SDR SDRAM organization (4M x 32) with 7ns speed grade and 3.3V supply, widely available drop-in alternative from a major DRAM vendor.
  • W9825G6JH-6 --: 128Mb SDR SDRAM in 4M x 32 configuration with compatible 3.3V interface; 6ns speed grade meets or exceeds the 7ns timing requirement.
  • AS4C4M32S-7TCN --: Pin-compatible 128Mb SDR SDRAM (4M x 32) at 7ns, specifically marketed as a legacy ISSI/Micron SDRAM replacement.
  • MT48LC4M32B2P-7 --: Same 128Mb SDR SDRAM organization (4M x 32) with 7ns speed grade and 3.3V supply; widely available drop-in equivalent from a major memory vendor.
