W25Q256FV
1. GENERAL DESCRIPTIONS
The W25Q256FV (256M-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 W25Q256FV array is organized into 131,072 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
W25Q256FV has 8,192 erasable sectors and 512 erasable blocks respectively. The small 4KB sectors
allow for greater flexibility in applications that require data and parameter storage. (See Figure 2.)
The W25Q256FV support the standard Serial Peripheral Interface (SPI), Dual/Quad I/O SPI as well as 2clocks instruction cycle Quad Peripheral Interface (QPI): Serial Clock, Chip Select, Serial Data I/O0 (DI),
I/O1 (DO), I/O2 (/WP), and I/O3 (/HOLD). SPI clock frequencies of up to 104MHz are supported allowing
equivalent clock rates of 208MHz (104MHz x 2) for Dual I/O and 416MHz (104MHz x 4) for Quad I/O when
using the Fast Read Dual/Quad I/O 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.
A Hold pin, Write Protect pin and programmable write protection, with top or bottom array control, provide
further control flexibility. Additionally, the device supports JEDEC standard manufacturer and device ID
and SFDP Register, a 64-bit Unique Serial Number and three 256-bytes Security Registers.
