Memory IC Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature grade. Ensure compatibility with the host system's voltage levels and SPI interface timing requirements. Confirm that the required dummy cycle settings align with the operating frequency for optimal performance.

Memory IC Selection Notes

Select this component when a 16 Mbit capacity is required with low power consumption and high-speed read capabilities. Consider the SOP-8 package constraints and verify that the host controller supports the necessary dual or quad SPI commands if higher throughput is needed. Evaluate the write protection needs against the available hardware and software locking options.

Memory IC FAQ

How is Quad SPI mode enabled on the GD25WQ16ESIGR?

Quad SPI mode is enabled by setting the Quad Enable (QE) bit in the Status Register to 1. When QE is set, the WP# and HOLD# pins function as bidirectional I/O pins IO2 and IO3.

What is the purpose of the Hold function?

The Hold function pauses serial communication without resetting the internal logic. It requires CS# to remain low and starts on the falling edge of the HOLD# signal while SCLK is low.
