IoT design: Why choose a Unique ID EEPROM?

Give every IoT device a unique identifier

Billions of IoT devices are connected, and every one of them needs an identity that can be trusted. ST’s Unique ID EEPROM goes beyond reliable storage to deliver that identity through a factory-programmed serial number embedded in a non-volatile memory. This hardware-based ID makes onboarding effortless, keeps fleets under control, and enables reliable cloud connections. It also helps make every IoT product traceable for life, prevents brands from counterfeits, and lets deployments scale without added complexity. Best of all, designers don’t need to add an extra component to the bill of materials to give their IoT device an identity.

ST’s Unique ID EEPROM is backed by rigorous qualification processes and high‑quality manufacturing, including extensive reliability testing and strict process control.

Why choose ST’s Unique ID EEPROM?

By embedding a guaranteed unique identifier directly in EEPROM, ST enables IoT manufacturers to simplify production, streamline onboarding, and maintain reliable device identity throughout the entire lifecycle.

	Benefits
Factory-programmed unique identifier	A unique, reliable identity assigned to every device without the risk of duplication Simplified manufacturing and reduced production time
Easy access to Unique ID EEPROM & data inside	Traceability over the full device lifetime
Standard serial interface (I²C)	Easy integration with MCUs and existing designs, with no forced redesign

How does a factory-programmed ID support your IoT lifecycle?

ST’s Unique ID EEPROM is a plug-and-play solution that easily fits into any IoT design. Each EEPROM has its own built-in unique ID, which the MCU reads and sends to the backend system. Cloud and management platforms can then use this stable ID for onboarding, updates, and fleet tracking throughout the product lifecycle.
