Application Scenarios & Design Considerations

16Meg x 8, 8Meg x16 128-MBIT SYNCHRONOUS DRAM

Alternative Part Number

  • MT48LC8M16A2P-6A --: Same 128Mb SDR SDRAM density in 8M x 16 organization with 3.3V LVTTL interface, widely available and pin-compatible in the same 54-pin TSOP package.
  • W9825G6KH-6 --: 128Mb SDR SDRAM organized as 8M x 16 with 3.3V supply and 54-pin TSOP II footprint, a common drop-in replacement for IS42S16800 devices.
  • AS4C8M16SA-6TIN --: Directly targets the IS42S16800 socket with 128Mb 8M x 16 SDR SDRAM, 3.3V operation and 54-pin TSOP II package, offered as a legacy-compatible alternative.
