Memory IC Procurement Notes

Verify the specific suffix 'EYIGY' against official datasheets to confirm the 8-WSON package and industrial temperature grade. Ensure compatibility with system voltage requirements between 2.7V and 3.6V. Confirm interface support for Quad I/O or DTR if high-speed access is required. Check for any obsolescence notices as some variants may be restricted for new designs.

Memory IC Selection Notes

Select this component when a 1Gb density is required in a small 8-WSON footprint. It is suitable for applications needing flexible interface options including DTR mode. Consider the -40°C to +85°C operating range for industrial environments. Verify that the 2.7V-3.6V supply voltage aligns with the target system design constraints.

Memory IC Part Context

This part belongs to the GD55B family of SPI NOR Flash memories, which are engineered for diverse market segments. The series offers densities ranging from 512Kb to 2Gb, targeting applications from consumer electronics to automotive systems. These devices emphasize high performance, low power consumption, and scalability for various embedded designs.

Memory IC Replacement Considerations

GD55B01GEFJRR: Offers identical electrical specifications but utilizes a 16-SOP package instead of 8-WSON. Requires PCB layout adaptation due to pin count and spacing differences. Other GD55B01 variants may differ in package type or temperature range; verify suffix codes carefully before substitution.
