The W25Q128JVSIQ was manufactured by Winbond. It comes in an SOIC-8 package type, featuring 8 pins and 8 terminals for connectivity. It boasts a wide operating temperature range, capable of functioning in extreme conditions from -40°C to 85°C. Additionally, the device operates within a power supply voltage range of 2.7V to 3.6V, making it versatile for various applications. Its interface is based on SPI, offering efficient data transfer and control. To facilitate easy integration into electronic circuits, the W25Q128JVSIQ employs a surface mount installation method.
The W250128JV is compatible with the standard Serial Peripheral Interface (SPI) as well as Dual/Quad I/O SPI, which includes Serial Clock, Chip Select, Serial Data I/O0 (D), I/O1 (DO), I/O2, and I/O3. It can handle SPI clock frequencies of up to 133MHz, which means it can achieve clock rates of 266MHz (133MHz x 2) for Dual I/O and 532MHz (133MHz x 4) for Quad I/O when using the Fast Read Dual/Quad I/O mode. These data transfer speeds can surpass those of regular Asynchronous 8 and 16-bit Parallel Flash memories. Furthermore, the device also supports JEDEC standard manufacturer and device identification (ID) as well as Serial Flash Discoverable Parameters (SFDP). It includes a unique 64-bit Serial Number and three Security Registers, each containing 256 bytes of data.

• Supports multiple read and write modes such as fast read, gain read, page program and block erase. These modes are suitable for different application scenarios, such as reading, writing and erasing data.
• Support low power mode. In standby mode, its power consumption is only 5μA, which makes W25Q128JVSIQ suitable for low-power application scenarios.
• Supports programmable read protection to prevent illegal access to memory. Setting a specific register bit in the memory can prevent the data in the memory from being illegally read and modified.
• Supports standard serial peripheral interface (SPI), including serial clock, chip select, serial data I/O0(DI), I/O1(DO), I/O2 and I/O3.
• Supports multiple supply voltage ranges, making it suitable for a variety of power supply environments, including battery-powered portable devices and other devices requiring different voltage ranges.
• Supports SPI clock frequency up to 133MHz. When using fast-read dual/quad I/O, the equivalent clock rate for dual I/O is 266MHz (133MHz x 2) and the equivalent clock rate for quad I/O is 532MHz (133MHz x 4). These transfer rates can exceed standard asynchronous 8-bit and 16-bit parallel flash memory.
