Design a Custom BoardAbout This Component
Serial flash memory IC with 2 megabits of storage capacity operating at up to 104 MHz SPI clock speed. Supports standard and dual I/O SPI protocols with 4KB sector erase granularity and operates from 2.5V to 3.3V supply. Commonly used for embedded system firmware storage, FPGA configuration, and data logging applications.
Package: SOIC-8 (3.9×4.9mm) · 8 pins
Why does this need a breakout?
An 8-pin SOIC with 1.27mm pitch is too fine for breadboards and hand-soldering without a microscope. A breakout board routes these pins to standard 0.1" headers, enabling rapid prototyping and reliable connections for op-amps, transceivers, and small power MOSFETs without requiring reflow equipment.
