Memory IC Procurement Notes

Verify the specific package variant required, as the base model designation covers multiple physical forms including SOP16, WSON8, and TFBGA24. Confirm the operating temperature grade matches the application environment, as options exist for -40°C to 85°C, -40°C to 105°C, and -40°C to 125°C. Ensure compatibility with the host controller's support for DTR or QPI modes if high-speed performance is necessary. Request the official datasheet for precise pinout and electrical characteristics relevant to the selected suffix.

Memory IC Selection Notes

Select this component when low-voltage operation between 1.65V and 2.0V is required for power-sensitive designs. Choose based on the necessary interface speed; utilize DTR mode for maximum throughput at 200MHz or standard Quad I/O for 166MHz. Consider the physical footprint constraints when choosing between WSON8, SOP16, or TFBGA24 packages. Ensure the design accounts for the specific thermal requirements corresponding to the chosen industrial temperature range option.

Memory IC Part Context

This part belongs to the GD25LT series of low-voltage SPI NOR Flash memories from GigaDevice. The series is designed for applications requiring high reliability and security features alongside compact form factors. The 'ME' designation typically indicates the specific density and feature set, while suffixes like 'Y2GY' denote the package type and temperature grade. This family targets modern embedded systems needing robust non-volatile storage with advanced error correction capabilities.

Memory IC Replacement Considerations

Publicly confirmed substitute part numbers for the GD25LT512MEY2GY are not available in the provided documentation. Users should consult GigaDevice's official cross-reference tools or contact the manufacturer directly for verified alternatives that match the specific package and temperature grade requirements.
