Single-Wire and UNI/O® Bus Serial EEPROM

A Tale of Two Pins


Using as few as two pins, our single-wire and UNI/O® bus serial EEPROMs can add the functionality your attachable end products have been missing. From authentication to calibration, these chips are ideal for replaceable attachments and consumable goods. They can also provide usage data to give insight on your products health, lifetime, and usage statistics. With as few as two pins (Serial I/O and GND) these products provide the verification, tracking, usage record, and counterfeit protection needed for your devices.

The single-wire devices can be mechanically attached (snap-in) to your end products. This means simplified manufacturing and greater flexibility with low-thermal plastic enclosures. They also offer extremely strong ESD protection making them suitable for direct contact from outside of the application.
