Design a Custom BoardAbout This Component
Serial EEPROM memory IC with 128 kilobit capacity, accessed via SPI interface. Supports standard SPI clock rates and includes write protection features. Commonly used for storing configuration data, calibration parameters, and firmware in embedded systems and consumer electronics 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.
