工作原理
The W25Q16JV uses a NOR flash array with multi-I/O SPI interface. The ‘J’ generation improves clock speed to 133MHz (vs 104MHz for earlier versions) and adds Fast Read Dual/Quad I/O commands. Quad I/O mode achieves 66MB/s throughput. The 2x3mm USON-8 package is the smallest available for serial flash, ideal for wearable and IoT devices with severe board space constraints. Program suspend/resume allows interleaved read and program operations. Security registers provide 256B OTP for device identification. Reset pin enables hardware reset of the device.
