STMicroelectronics
STMicroelectronics N.V.
Overview
ST is a major semiconductor company with a growing RFID portfolio. Their ST25 family covers both HF/NFC and UHF, competing with NXP on the NFC side. ST chips are particularly strong in industrial applications and dynamic NFC tags that can be powered by the reader's RF field to perform sensing functions.
Known for
ST25 NFC/RFID chip family, including dynamic NFC tags with I2C interfaces that bridge RFID and microcontroller worlds.
Key products
Dynamic NFC/RFID tag IC with I2C interface. Allows a microcontroller to write data that an NFC phone can read – used in smart sensors, configuration, and energy harvesting.
NFC/HF tag ICs with tamper detection and digital signature. Used for brand authentication and product provenance.
NFC reader chips for embedding contactless reading into devices – POS terminals, IoT gateways, and mobile accessories.
UHF RAIN RFID reader silicon for integration into fixed and handheld readers.
