W25Q128 LARGE CAPACITY FLASH STORAGE MODULE SPI INTERFACE

The W25Q128FV (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 4mA active and 1µA for power-down. All devices are offered in space-saving packages. The W25Q128FV array is organized into 65,536 programmable pages of 256-bytes each. bytes can be programmed at a time.

Pages can be erased in groups of 16 (4KB sector erase), groups to 256 of 128 (32KB block erase), groups of 256 (64KB block erase), or the entire chip (chip erase). The W25Q128FV 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.

The W25Q128FV support the standard Serial Peripheral Interface (SPI), Dual/Quad I/O SPI as well as 2-clocks instruction cycle Quad Peripheral Interface (QPI): Serial Clock, Chip Select, Serial Data 1/O0 (DI), I/01 (DO), 1/02 (WP), and 1/03 (/HOLD). SPI clock frequencies of up to 104MHz are supported allowing equivalent clock rates of 208MHz (104MHz x 2) for Dual 1/0 and 416MHz (104MHz x 4) for Quad 1/O when using the Fast Read Dual/Quad VO and QPI instructions.

These transfer rates can outperform standard Asynchronous 8 and 16-bit Parallel Flash memories. The Continuous Read Mode allows for efficient memory access with as few as 8-clocks of instruction-overhead to read a 24-bit address, allowing true XIP (execute in place) operation.
