Memory IC FAQ

What is the difference between Standard SPI and Dual Output modes?

Standard SPI uses four signals (SCLK, CS#, SI, SO) for data transfer. Dual Output mode utilizes two bidirectional I/O pins (IO0 and IO1) to transfer data at twice the rate of standard SPI, achieving up to 160 Mbits/s.

How does the hardware write protection work?

Hardware write protection is enabled by driving the WP# pin low. This locks the Block Protect bits (BP2-BP0) and the Status Register Protect (SRP) bit, preventing any changes to the protected memory areas via software commands.
