STMicroelectronics Offers NFC Technology for Secure Contactless Payments, IoT

STMicroelectronics (ST) has announced the availability of its latest-generation Near Field Communication (NFC) devices for contactless payments and data exchange. The new devices include the ST21NFCD NFC controller, as well as two new members in the company's ST54 System-in-Package (SiP) family.

The ST21NFCD chip features active load modulation for faster, smoother transactions over longer distances, the company reports, resulting in better user experiences with mobiles, wearables or Internet of Things devices. It supports card emulation, reader-writer and peer-to-peer communication modes, and contains eFlash to permit full firmware update. It supports the NFC Forum's NCI 2.0 specification, which simplifies software development for interacting with NFC tags and supports batching and autonomous exchanges to minimize communication overheads.

The IC also meets NFC Forum type 1-5 tag specifications, ISO/IEC 18092 NFC Interface and Protocol (NFCIP), and payment standards including EMVCo latest revisions. It is pre-certified in accordance with the Global Certification Forum (GCF) and PTCRB for integration in mobile devices, and can enable handsets to read Mifare Classic encrypted tags.

Built-in power management and battery-voltage monitoring minimize any impact on runtime in a host-system, such as a smartphone. According to ST, high RF sensitivity (which allows the use of miniaturized antennas), the option to use an external clock source instead of a crystal, and the chip's high output power help to reduce bill-of-materials and board footprint.

ST's latest ST54 Systems-in-Packages—the ST54F and the ST54H—contain the ST21NFCD NFC controller and an embedded secure element (eSE). The eSE is an ST33 secure microcontroller certified to high security standards, including Common Criteria EAL5+ and EMVCo for financial applications, which ensures strong protection against duplication and hacking. It leverages ARM's SecurCore SC300 core and supports secure operating systems running Java Card and GlobalPlatform.

The ST54F integrates the ST21NFCD with the widely deployed ST33G1M2 secure element, with up to 1.28 megabytes of eFlash. The ST54H embeds a more advanced ST33J2M0 eecure element, with up to 2 megabytes of eFlash and twice the performance of the ST33G1M2, to connect with new digital secure applications from service providers.
