Application Scenarios & Design Considerations

32Meg x 8, 16Meg x16 256-MBIT SYNCHRONOUS DRAM

Alternative Part Number

  • MT48LC16M16A2P-6A --: 16M x 16 SDR SDRAM in 54-pin TSOP II, same 166 MHz speed grade and 3.3V interface, widely available drop-in equivalent.
  • W9825G6KH-6 --: 16M x 16 SDR SDRAM with matching 166 MHz timing and 54-pin TSOP package, a common pin-compatible substitute for ISSI SDR parts.
  • AS4C16M16SA-6TIN --: 16M x 16 SDR SDRAM, 166 MHz, 54-pin TSOP II, explicitly positioned as a cross-reference replacement for IS42S16160 series devices.
