W25Q256JVEN

The W25Q256JV (256M-bit) Serial Flash memory provides a storage solution for systems with limited space, pins, and power. The 25Q series offers flexibility and performance 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 runs from a single 2.7V–3.6V power supply, with current consumption as low as 1μA in power-down mode. All devices are offered in space-saving packages.

The memory array is organized into 131,072 pages of 256 bytes each. Up to 256 bytes can be programmed at once.
Erase options:

• 4KB sectors (16 pages),

• 32KB blocks (128 pages),

• 64KB blocks (256 pages),

• or full chip erase.

In total: 8,192 erasable sectors and 512 erasable blocks.
The small 4KB sectors give high flexibility for parameter/data storage.

The W25Q256JV supports:

• standard SPI,

• Dual SPI,

• Quad SPI,
  with clock rates up to 133MHz. This equals:

• 266MHz (Dual I/O)

• 532MHz (Quad I/O)
  when using Fast Read mode — faster than many asynchronous parallel Flash devices.

Additional features include:

• JEDEC ID + SFDP register,

• 64-bit unique serial number,

• three 256-byte security registers.
