Memory IC Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature range. Ensure compatibility with host controller voltage levels and SPI mode settings. Check for any recent product change notices that may affect pinout or electrical characteristics before finalizing procurement.

Memory IC Selection Notes

Select this component when a 16M-bit capacity with high-speed quad I/O support is required. Consider the SOP-8 package constraints for board space. Evaluate the need for specific security features like OTP locks or top/bottom block protection. Confirm that the operating temperature range meets the application environment requirements.

Memory IC Part Context

This part belongs to the GD25Q16E series of uniform sector dual and quad serial flash memories. The series offers various package options including SOP-8, USON-8, and WSON-8. It is designed for applications requiring reliable non-volatile storage with fast read speeds and robust data protection features.

Memory IC Replacement Considerations

Check for direct substitutes within the GD25Q16 family with different suffixes indicating alternative packages or temperature grades. Verify pin compatibility and electrical specifications before substituting with other manufacturers' 16M-bit SPI NOR flashes.

Memory IC FAQ

What is the difference between the HOLD# and WP# pins?

The HOLD# pin pauses serial communication without deselecting the chip, while the WP# pin provides hardware-based write protection for the status register and memory array.

How is Quad SPI mode enabled?

Quad SPI mode is enabled by setting the Quad Enable (QE) bit in the Status Register to 1 using the Write Status Register command.
