Design a Custom BoardAbout This Component
128-megabit serial flash memory with dual and quad SPI interface support, operating at 3.3V. Features fast read speeds and supports both standard SPI and higher-speed quad SPI modes for efficient data transfer. Commonly used for firmware storage, configuration data, and bootloader applications in embedded systems and industrial devices.
Package: SOICW-8 (5.3mm wide) · 8 pins
Why does this need a breakout?
This SOIC-8 package is too small to hand-solder reliably and incompatible with breadboards. A breakout board brings 1.27mm pitch pins to standard 0.1-inch spacing, enabling prototyping without specialized equipment. Ideal for memory and sensor ICs that demand convenient development while preserving the compact footprint.
