W25Q40BWSSIG【PDF 1/2 页】IC FLASH SPI 4MBIT 8SOIC

Winbond's W25X and W25Q SpiFlash? Multi-I/O Memories feature the popular Serial Peripheral Interface (SPI), densities

from 512K-bit to 256M-bit, small erasable sectors and the industry's highest performance. The W25X family supports

Dual-SPI effectively doubling standard SPI clock rates. The W25Q family is a "superset" of the 25X family with Dual-I/O and

Quad-I/O SPI for even higher performance. Clock rates up to 104MHz achieve an equivalent of 416MHz (50M-Byte/S transfer

rate) when using Quad-SPI. This even surpasses asynchronous Parallel Flash memories while using fewer pins and less

space. Faster transfer rates mean controllers can execute code (XIP) directly from the SPI interface or further improve boot

time when shadowing code to RAM. Some SpiFlash devices offer the new Quad Peripheral Interface (QPI) supporting true

Quad Commands for improved XIP performance and simpler controller circuitry. Additionally, new ultra-small form-factor

packages are ideal for space constrained mobile and handheld applications.
