Memory IC Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and pin configuration. Ensure that the voltage supply and interface requirements match the system design specifications before procurement. Confirm compliance with relevant environmental standards as listed in the product datasheet.

Memory IC Selection Notes

Select this component when a 128 Mbit capacity with uniform sector architecture is required. Consider the TFBGA-24 package for space-constrained surface-mount designs. Verify compatibility with host controllers supporting Quad SPI modes if high-speed data retrieval is necessary. Check thermal ratings against the intended operating environment.

Memory IC Part Context

This part belongs to the GD25Q128E series of uniform sector dual and quad serial flash memories. The series is designed for high-performance code execution and data storage applications.

Memory IC FAQ

What is the function of the QE bit in the status register?

The Quad Enable (QE) bit allows the device to operate in Quad SPI mode. When set to 1, it enables the use of IO2 and IO3 pins as bidirectional data I/O lines instead of their default functions.

How does the HOLD function work on this device?

The HOLD function pauses serial communications without resetting the internal logic. It requires CS# to remain low and activates on the falling edge of the HOLD# signal while SCLK is low. Communication resumes when HOLD# goes high.
