Memory IC FAQ

What is the maximum data transfer rate supported by the BY25Q64AS?

The device supports data transfer rates up to 432 Mbits/s in Quad I/O mode.

How does the hardware write protection work?

Hardware write protection is enabled by driving the /WP pin low while the Status Register Protect bits are configured appropriately, locking the status register and protected memory areas.
