Application Scenarios & Design Considerations

4Meg x 32 128-MBIT SYNCHRONOUS DRAM

Alternative Part Number

  • MT48LC4M32B2P-6A --: Same 128Mb SDR SDRAM organization (4M x 32) in a 90-ball TFBGA package with 166MHz speed grade, a direct functional equivalent to the IS42S32400B-6BL.
  • W9825G6KH-6 --: 128Mb SDR SDRAM organized as 4M x 32 with 166MHz operation, pin-compatible with the IS42S32400B series and widely used as a drop-in replacement.
  • AS4C4M32S-6BIN --: Alliance Memory specializes in legacy SDRAM replacements; this 4M x 32 128Mb SDR SDRAM at 166MHz matches the density, organization and speed of the original ISSI device.
