Memory IC Procurement Notes

Verify the specific suffix ETAGR against official manufacturer documentation to confirm package type and tape-and-reel specifications. Confirm availability status as distribution channels may indicate limited stock or regional sales restrictions. Ensure compliance with local import regulations and environmental directives such as RoHS before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a 4 Mbit capacity with 133 MHz Quad SPI support is required. Ensure the design accommodates the 2.7 V to 3.6 V operating voltage range. Verify that the SOP-8 package dimensions fit the target PCB layout constraints. Consider thermal management requirements for active read currents up to 20 mA during high-speed operations.

Memory IC Part Context

This part belongs to the GD25Q series of SPI NOR flash memories from GigaDevice. The series offers various densities and interface options including Standard, Dual, and Quad SPI. These devices are designed for general-purpose non-volatile storage applications requiring reliable data retention and fast read access speeds across industrial temperature ranges.

Memory IC Replacement Considerations

Check for direct pin-compatible alternatives within the same GD25Q family. Verify if higher density variants like GD25Q80 or lower density parts meet functional requirements. Ensure any substitute maintains compatible voltage levels and interface protocols.
