Reliable SPI Flash Memory for Space-Conscious Designs: Boost Performance and Flexibility in Embedded Applications
The 128Mbit Serial Flash Memory SPI Breakout - W25Q128JWSIQ is a highly efficient, solder-free memory solution tailored for developers working on embedded systems, portable electronics, and industrial automation. Designed around the Winbond W25Q128JWSIQ IC, this breakout board (BO-10114) offers exceptional performance with its SPI-based data interface, enabling fast, flexible, and space-saving integration without the need to solder chips directly onto a PCB.
With support for Dual/Quad SPI I/O, standard SPI commands, and clock speeds of up to 133MHz, this breakout module ensures rapid data transfers and low latency read/write operations. The memory is structured into 65,536 pages of 256 bytes each, allowing precise control over programming and erasure processes, which include 4KB sectors, 32KB and 64KB blocks, and full-chip erase options. This modularity makes the breakout an ideal solution for prototyping, development, and even small-scale production where board space and power efficiency are critical concerns.
