Memory IC FAQ

What is the default state of the Quad Enable (QE) bit?

The QE bit is set to 1 as default and cannot be changed, enabling Quad SPI operation immediately upon power-up without additional configuration commands.

How does the device handle address modes?

The device supports both 3-byte and 4-byte address modes. The initial mode is determined by the ADP bit in Status Register 3, which can be configured to power up in either mode.

What security features are included?

The device includes software write protection via Block Protect bits, 128-bit Unique ID, Serial Flash Discoverable Parameters (SFDP), and One-Time Programmable (OTP) Security Registers with lock bits.
