Memory IC FAQ

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 bidirectional I/O pins IO2 and IO3, enabling Quad SPI operations. When QE is 0, these pins retain their dedicated write protect and hold functions.

What is the purpose of the Dummy Configuration (DC) bit?

The DC bit configures the number of dummy cycles inserted between the address phase and data output phase. This adjustment is necessary to maintain signal integrity at higher clock frequencies, specifically when operating at 133 MHz.
