Winbond W25Q256JVEIQ 3V 256Mbit Serial Flash Memory With

DUAL/QUAD SPI
For Industrial & Industrial Plus Grade
The W25Q256JV supports standard SPI, Dual SPI and Quad SPI operation. Standard SPI instructions
use the unidirectional DI (input) pin to serially write instructions, addresses or data to the device on the
rising edge of the Serial Clock (CLK) input pin. Standard SPI also uses the unidirectional DO (output) to
read data or status from the device on the falling edge of CLK.

GENERAL DESCRIPTIONS

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 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 W25Q256JV 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
W25Q256JV 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.

The W25Q256JV 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 W25Q256JV
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. 

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.
