Memory IC Procurement Notes

Verify the specific package variant against the datasheet, as the ENEGR suffix corresponds to the USON-8 (3x4mm) package. Confirm that the required operating voltage range aligns with the 1.65V to 3.6V specification. Ensure compatibility with the host controller's SPI interface modes, particularly if utilizing Quad I/O commands which require setting the QE bit in the status register.

Memory IC Selection Notes

Select this component when a low-voltage operation down to 1.65V is required alongside high-speed Quad SPI access. It is suitable for applications needing robust data protection through hardware WP# pin locking or software block protection. Consider this part for designs requiring a small footprint using the USON-8 package while maintaining industrial-grade endurance and data retention specifications.

Memory IC Part Context

The GD25WQ64E series belongs to GigaDevice's Uniform Sector Dual and Quad Serial Flash family. This series is designed for high-performance embedded applications requiring reliable non-volatile storage. The GD25WQ64ENEGR specifically utilizes the USON-8 (3x4mm) package, offering a compact solution for space-constrained designs compared to larger SOP or WSON packages available within the same product line.

Memory IC FAQ

How does the Quad Enable (QE) bit affect the HOLD# and WP# pins?

When the QE bit is set to 1, the HOLD# and WP# pins function as bidirectional I/O pins (IO3 and IO2) for Quad SPI operations, disabling the standard Hold and Write Protect functions.

What is the purpose of the Dummy Configuration (DC) bit in Status Register 3?

The DC bit configures the number of dummy cycles between the address phase and data output phase during Fast Read commands, ensuring proper timing at higher clock frequencies like 104 MHz.
