Memory IC Procurement Notes

Verify current availability status as the component lifecycle is listed as obsolete or discontinued. Confirm that the specific suffix '18I' corresponds to the required 533 MHz speed grade and industrial temperature rating. Ensure compatibility with existing PCB footprints for the FBGA-144 package before finalizing procurement plans due to potential supply chain constraints.

Memory IC Selection Notes

Select this part when low latency performance is critical alongside high bandwidth requirements in demanding environments. The 18-bit data width suits applications needing error correction or wide data buses. Verify that the system power rails can maintain stability between 1.7 V and 2.63 V. Consider the physical dimensions of the FBGA-144 package during mechanical design integration.

Memory IC Part Context

This component belongs to the GS4576C18GM series of Low Latency DRAM devices from GSI Technology.
