The SoC is said to deliver “performance-boosting” integration for mobile and IoT devices, with the added benefit of ST’s software-partner ecosystem for smoother user experiences in mobile payments and e-ticketing transactions.
ST state that the single-chip ST54J 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 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 come from the space savings of integrating three key functions onto a single chip according to ST. In addition, ST said it 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 minimise the thickness of new smartphone generations.
