Design a Custom BoardAbout This Component
Dynamic NFC/RFID tag IC with 4 kbit EEPROM memory, dual I2C and ISO15693 contactless interfaces, and fast transfer mode. Operates 1.8-5.5V with 1 MHz I2C support and up to 53 kbit/s RF data rates. Includes configurable password protection, energy harvesting output, and 40-year data retention across industrial temperature ranges.
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.
