Memory IC FAQ

What is the maximum clock rate for Fast Read operations?

The maximum clock rate for Fast Read (Serial) operations is 108MHz with a 30pF load.

How does the Quad Enable (QE) bit affect pin functionality?

When the QE bit is set to 1, the /WP and /HOLD pins function as IO2 and IO3 respectively for Quad SPI data input/output.

What are the available erase times for different operations?

Typical erase times are 50ms for Sector Erase, 0.15s or 0.25s for Block Erase, and 15s for Chip Erase.
