Application Scenarios & Design Considerations

128M(4Mx32) GDDR SDRAM

Alternative Part Number

  • MT46V32M16P-5B --: Same 512Mb DDR SDRAM density with 32M x16 organization and 4ns-class speed grade, widely available and pin-compatible in function.
  • K4H511638D-UCB3 --: 512Mb DDR SDRAM in 32M x16 configuration with comparable 4ns speed bin, a common drop-in alternative from a major DRAM vendor.
  • IS43R16320D-5BL --: 512Mb DDR SDRAM organized as 32M x16 with similar timing, suitable as a functional replacement when Hynix parts are unavailable.
  • MT46V32M8TG-5B --: 32M x 8 DDR SDRAM in the same 400 mil TSOP package with comparable speed grade, a well-established drop-in style alternative from a major DRAM vendor.
  • K4H280838E-TCB0 --: 256Mb DDR SDRAM organized 32M x 8 with similar timing and package, widely available and commonly used as a substitute for Hynix DDR parts.
  • IS43R83200B-5TL --: 256Mb DDR SDRAM 32M x 8 in TSOP, pin-compatible with the original and offered by a vendor known for legacy DRAM replacements.
