• Enables execute-in-place (XiP) operations

Memory IC Applications

• Firmware storage in embedded systems
• Code execution directly from memory
• Data logging applications
• Configuration parameter storage

Memory IC Procurement Notes

Verify the specific suffix ENIGR against official manufacturer documentation to confirm the USON-8 package dimensions and lead finish specifications. Ensure compatibility with the required operating voltage range and interface modes before integration into the design.

Memory IC Selection Notes

Select this component when a compact surface-mount footprint is required alongside high-speed read capabilities. Consider the Quad SPI support if higher data throughput is necessary compared to standard SPI implementations.

Memory IC Part Context

This part belongs to the GD25Q16E series of uniform sector dual and quad serial flash memories. The series provides non-volatile storage solutions designed for applications requiring reliable data retention and fast access speeds within a small physical profile.

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 WP# and HOLD# pins to function as bidirectional I/O pins IO2 and IO3.

How does the Hold function operate?

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