Design a Custom BoardAbout This Component
SPI-compatible serial EEPROM with 2,048 bits (256 bytes) of non-volatile memory in 8-SOIC package. Operates at clock rates up to 20 MHz with 1.8V to 5.5V supply range, featuring 8-byte page writes, block write protection, and write-protect pin. Rated for 1,000,000 write cycles with 100-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.
