W25Q256JWEIQ 1.8V 256Mb Serial FLASH-NOR Memory IC with dual quad SPI
Product Description Of W25Q256JWEIQ
The W25Q256JWEIQ (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 1.7V to 1.95V power supply with current consumption as low as 1µA for power-down. All devices are offered in space-saving packages.
The W25Q256JWEIQ 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 W25Q256JWEIQ 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 W25Q256JWEIQ supports the standard Serial Peripheral Interface (SPI), and a high performance Dual/Quad output as well as 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 up to 133MHz are supported allowing equivalent clock rates of 532MHz (133MHz x 4) for Quad I/O when using the SPI Fast Read Quad I/O instructions. These transfer rates can outperform standard Asynchronous 8 and 16-bit Parallel Flash memories.
