Memory IC Procurement Notes

Verify the specific suffix 'IGR' corresponds to the SOP-8 package and reel/cut-tape packaging format required for your assembly line. Confirm that the voltage range of 2.7V to 3.6V aligns with your system's power supply design. Ensure compatibility with the 133 MHz clock speed requirements if utilizing high-speed read commands. Check for RoHS compliance documentation if required by your manufacturing standards.

Memory IC Selection Notes

Select this component when a 16M-bit capacity is sufficient for firmware or data storage needs. It is suitable for designs requiring high-speed read performance via Quad SPI interface. Consider its wide operating temperature range if deployed in industrial environments. Evaluate the need for hardware write protection features before finalizing the schematic design to ensure data integrity during operation.

Memory IC Part Context

This part belongs to the GD25Q16E series of dual and quad serial flash memories. It shares architectural similarities with other members of the GD25Q family but differs in specific package options and operational parameters. The 'G' suffix typically denotes the SOP-8 package variant, while 'R' indicates tape and reel packaging. It serves as a non-volatile storage solution within GigaDevice's broader memory portfolio.
