Application Scenarios & Design Considerations

16Mx32 512Mb SYNCHRONOUS DRAM

Alternative Part Number

  • MT48LC32M16A2P-75 --: 32M x16 SDR SDRAM in TSOP-54, same 512Mb density and 133MHz speed grade, widely available drop-in functional equivalent.
  • W9825G6KH-6 --: 256Mb x16 SDR SDRAM with compatible 3.3V interface and 166MHz rating, covers the 75ns timing requirement and is a common ISSI substitute.
  • AS4C32M16SB-7TCN --: 32M x16 SDR SDRAM in TSOP-54, pin-compatible with IS42S32160C and rated at 143MHz, offered as a direct second-source replacement.
