What is the W25Q128JVSIQ?
The W25Q128JVSIQ (128M-bit) Serial Flash memory provides a storage solution for systems with limited space, pins, and power. The 25Q series offers flexibility and performance well beyond ordinary Serial Flash devices. They are ideal for code shadowing to RAM, executing code directly from Dual/Quad SPI (XIP), and storing voice, text, and data. The device operates on a single 2.7V to 3.6V power supply with current consumption as low as 1µA for power-down. All devices are offered in space-saving packages.
The W25Q128JVSIQ array is organized into 65,536 programmable pages of 256-bytes each. Up to 256 bytes can be programmed at a time. Pages can be erased in groups of 16 (4KB sector erase), groups of 128 (32KB block erase), groups of 256 (64KB block erase), or the entire chip (chip erase). The W25Q128JV has 4,096 erasable sectors and 256 erasable blocks respectively. The small 4KB sectors allow for greater flexibility in applications that require data and parameter storage. (See Figure 2.)
The W25Q128JVSIQ supports the standard Serial Peripheral Interface (SPI), Dual/Quad I/O SPI: Serial Clock, Chip Select, Serial Data I/O0 (DI), I/O1 (DO), I/O2, and I/O3. SPI clock frequencies of W25Q128JVSIQ of up to 133MHz are supported allowing equivalent 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. These transfer rates can outperform standard Asynchronous 8 and 16-bit Parallel Flash memories.

Voltage - Supply (Max) is a parameter in electronic components that specifies the maximum voltage that can be safely applied to the component for proper operation. This parameter is crucial for ensuring the component's longevity and preventing damage due to overvoltage conditions. Exceeding the maximum supply voltage can lead to component failure, reduced performance, or even permanent damage. Designers must carefully consider this parameter when selecting components and designing circuits to ensure reliable and safe operation within the specified voltage limits.
3.6V - Voltage - Supply (Min)
Voltage - Supply (Min) is a parameter in electronic components that specifies the minimum voltage required for the component to operate within its specified performance range. This parameter indicates the lowest voltage level that can be safely applied to the component without causing malfunctions or damage. It is crucial to ensure that the supply voltage provided to the component is equal to or higher than the specified minimum voltage to guarantee proper functionality and reliability. Failure to meet this requirement may result in erratic behavior, reduced performance, or even permanent damage to the component.
