W25Q256JVEIM

The W25Q256JV is a 256M-bit Serial NOR Flash memory developed by Winbond, designed to provide a storage solution for systems with limited space, pins, and power. This innovative device is part of the 25Q series, which offers flexibility and performance that surpass ordinary Serial Flash devices. Ideal for code shadowing to RAM, executing code from Dual/Quad SPI (XIP), and storing voice, text, and data, the W25Q256JV operates on a single 2.7V to 3.6V power supply with current consumption as low as 1μA for power-down. This device is also offered in various space-saving packages to accommodate different applications.

Function & Applications

The W25Q256JV is an ideal choice for applications requiring data and parameter storage due to its small 4KB erasable sectors. It supports the standard Serial Peripheral Interface (SPI), Dual/Quad I/O SPI, and has 8,192 erasable sectors and 512 erasable blocks. This device allows for true XIP (execute in place) operation, offering high-performance data transfer rates that can outperform standard Asynchronous 8 and 16-bit Parallel Flash memories.

Performance Parameters

This high-performance Serial Flash supports 133MHz standard/dual/quad SPI clocks, offering up to 66MB/s continuous data transfer rate. Additionally, it offers up to 100K program-erase cycles per sector and more than 20 years of data retention, ensuring reliability and longevity for your applications.
