Winbond W25Q40RVSNJQ

The W25Q40RV (4M-bit) serial flash provides a storage solution for systems constrained by space, pin count, and power. The 25Q series offers far greater flexibility and performance than standard 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 from a single 2.7V to 3.6V supply, with current consumption as low as 1μA in power-down mode. The W25Q40RV array is organized as 2,048 programmable pages of 256 bytes each. Up to 256 bytes can be programmed at a time. The W25Q40RV features 128 erasable sectors, 16 erasable 32KB blocks, and 8/4 erasable 64KB blocks. The small 4KB sector size provides greater flexibility for applications requiring data and parameter storage. The W25Q40RV supports Standard SPI as well as high-performance Dual/Quad output and Dual/Quad I/O SPI: Serial Clock, Chip Select, Serial Data I/O0 (DI), I/O1 (DO), I/O2 (WP), and I/O3 (/HOLD). SPI clock frequencies up to 133MHz are supported, with Fast Read Dual/Quad I/O instructions enabling equivalent clock rates of 266MHz (133MHz x 2) for Dual I/O and 532MHz (133MHz x 4) for Quad I/O. These transfer rates can surpass standard asynchronous 8-bit and 16-bit parallel flash. The Read Command Bypass mode enables true XIP (Execute-In-Place) operation by allowing 24-bit address reads with an instruction overhead of as few as 8 clocks for efficient memory access. The device provides a Hold pin, a Write Protect pin, and programmable write protection functionality.
