Main models:


In addition to providing memory chips, we have been deeply involved in the storage field for 15 years. We can help customers find alternative solutions for memory chip models, control costs, match upstream and downstream resources, and provide technical support. Feel free to inquire for more information.

I can provide you with a brief introduction to the Winbond 25Q256JV flash memory chip:

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.

Here are some key features of the Winbond W25Q256JVEQ:

•Single/Dual/Quad SPI operations
• 3 or 4-Byte Addressing Modes
• Uniform 4KB erasable sectors & 32KB/64KB erasable blocks
• 131,072 pages (256 bytes), page program in 0.7mS (typ.)
• Continuous Read with 8/16/32/64 Byte Wrap
• Clock operation up to 133MHz (266/532MHz equivalent with Dual/Quad SPI)
• 2.7 to 3.6V power supply
• Package:16-pin SOIC 300-mil, 24-ball TFBGA 8×6-mm (6×4 Ball Array),8-pad WSON 8×6-mm, 24-ball TFBGA 8×6-mm (5×5 Ball Array)

If you have any specific questions or if you need the complete datasheet, please provide me with your email address, and I’ll be happy to send it to you.
