Feature: 1. DOUBLE OPERATING FREQUENCY: The W25X series support dual SPI dual input mode, which is equivalent to standard SPI. The double operating frequency of the W25Q series is an advanced version of the 25x series 2. HIGHER EFFICIENCY: Support four level L or O, SPI four wire output and input mode can provide higher efficiency 3. FOUR TIMES OPERATING EFFICIENCY: The operating frequency of 104MHz is equal to 416MHz (50mbytes/sec), which is equivalent to four times the operating efficiency of ordinary single wire SPI 4. FEWER PIN PACKAGES: The W25Q series is not only more effective than parallel flashing, but also offers fewer pin packages 5. FASTER STARTUP TIME: Faster transfer rate means that the controller can be directly executed via SPI connection(XIP), or speed up the copying of code to RAM faster for faster startup time Specification: Item Type: FLASH Storage Module Product Capacity: 32M-BIT/4M-BYTE Clock Frequency: ≤104MHZ Working Voltage: 2.7~3.6V Product Size: Approx. 14 x 15mm / 0.55 x 0.59in. Package List: 1 x FLASH Storage Module
