Function: 1. DUAL OPERATION FREQUENCY: The W25X series supports dual SPI dual input mode, which is equivalent to standard SPI. The dual operation frequency of the W25Q series is an advanced version of the 25x series. 2. HIGHER EFFICIENCY: Support for four-level L or O, SPI four-wire output and input mode can provide higher efficiency. 3. FOUR TIMES OPERATION EFFICIENCY: The operation frequency of 104MHz is equivalent to 416MHz (50MB/sec), which is equivalent to four times the operation efficiency of ordinary single-wire SPI. 4. FEWER PIN PACKAGES: The W25Q series is not only more efficient than parallel flashing but also offers fewer pin packages. 5. FASTER BOOT TIME: Faster transfer speed means the controller can run directly via SPI connection (XIP), or speed up the copying of code to RAM faster for faster boot time.
