The single-chip ensures faster contactless interaction than a discrete chipset by eliminating performance-limiting off-chip data exchanges between the Secure Element and NFC controller. In addition, a faster, state-of-the-art core for each function further accelerates contactless transactions with mobile terminals and enhances roaming by supporting secure-element cryptographic protocols used worldwide, including FeliCa and MIFARE. Packaging and design flexibility comes from the space savings of integrating three key functions onto a single chip. In addition, ST used its NFC booster technology to enhance the performance of the NFC controller, allowing it to establish robust contactless connections with a small-size antenna, allowing designers even more generous freedom to manage space inside the device and minimize the thickness of new smartphone generations.
The ST54J comes with NFC firmware and the GlobalPlatform V2.3 secure element Operating System, for best-in class cryptographic performance and optimum eSIM interoperability. The OS also allows flexible configurations to support eSE-only or combined functionality.
