Design a Custom BoardAbout This Component
256-Kbit serial EEPROM with I2C interface operating from 2.5V to 5.5V. Features 64-byte page write buffer, 5ms page write time, and supports up to eight devices on the same bus. Ideal for low-power data storage in industrial and consumer applications with >1M erase/write cycles and >200 year data retention.
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.
