The ST54J is a single-die solution integrating a contactless front-end (CLF) and a secure element called ST54J_CLF and ST54J_SE. It is designed for integration in mobile devices and NFC-compliant products.
The ST54J_CLF includes near-field communication (NFC) functions in the three operating modes: Card Emulation, Reader/Writer and Peer-to-Peer communication.
It is best in class in terms of RF output power (up to 2 W). With its outstanding output power and optimized efficiency, the ST54J driver can be connected to metal frame antennas. Thanks to improved low-power card detection sensitivity, in Reader/Writer mode, the ST54J_CLF operating in low-power mode is capable of detecting the presence of a card/tag from a distance greater than the Reader mode performance.
In Card Emulation mode, the ST54J_CLF is capable of operating without an external quartz or an external reference clock source, contributing to further reducing the current consumption of the system in low-power mode. Moreover, thanks to its improved field detection sensitivity, the ST54J_CLF is capable, in low-power mode, of detecting the presence of a reader RF field from a distance greater than the CE mode performance.
The ST54J_SE is a serial access microcontroller designed for secure mobile applications. It incorporates the most recent generation of Arm® processors for embedded secure systems. The SecurCore® SC300™ 32-bit RISC core is built on the Cortex®-M3 core, with additional security features to help protect against advanced forms of attacks.
