Application Scenarios & Design Considerations

128Mb DDR SDRAM

Alternative Part Number

  • MT48LC8M16A2P-6A --: 128Mb SDR SDRAM in 54-pin TSOP, same 8M x16 organization and 3.3V interface as the original, widely available and pin-compatible replacement.
  • IS42S16800E-6TL --: 128Mb SDR SDRAM organized as 8M x16 in TSOP-II, functionally equivalent to the Samsung part with similar speed grade and voltage.
  • W9825G6JH-6 --: 256Mb SDR SDRAM in 8M x16 x4 banks configuration, drop-in compatible for most 128Mb SDR designs and readily stocked as an alternative source.
