STMicroelectronics ST54L combined NFC controller and secure element IC

STMicroelectronics has released the ST54L combined NFC controller and secure element IC, which enables mobile devices like smartphones, smart wearables and tablets to access security-protected contactless ticketing and payment services through the STPay-Mobile platform.

The ST54L can host multiple services including NFC mobile payments, mobile transit ticketing, access-control applications such as Digital Car Key and converged services requiring an embedded SIM (eSIM). The chip comes with the Thales mobile secure operating system running on the embedded secure element, a combination cooperatively developed by ST and Thales.

The ST54L chip is designed to enhance NFC RF performance and increase non-volatile storage. The larger memory permits loading extra services on the device while providing generous storage for users to download additional eSIM profiles to support multiple enabled profiles (MEP) or secure applications.

The ST54L is in mass production now and is part of the Google Pixel 8 phones. The chip has also been validated by several major mobile platform makers. STMicroelectronics manufactures the ST54L chips using proprietary embedded Flash technology at its own wafer-fabrication plant and relies on a full in-house supply chain.
