STMicroelectronics (ST; NYSE: STM), the world's leading semiconductor supplier, has introduced the most popular wristbands, watches, or fashion accessories for convenience and security across multiple electronic applications Contact-based semiconductor technology. STMicroelectronics' industry-leading ST53G system packaging solution combines market-leading NFC and secure transactional silicon in the same package.
As consumers become more comfortable with secure transactions using smart devices, the card merchant intends to enter the non-contact wearable device market with payment, fare collection and access control, but these are difficult to achieve in wearable products where size and cost are limited Function, because the traditional non-contact IC card is composed of two independent devices of NFC radio frequency chip and security chip, it needs more space and the design is complicated. In addition, the small size of the wearable device determines that it can only use small antennas with limited communication capabilities.
STMicroelectronics' new ST53G system package overcomes these technical barriers by integrating miniaturized and performance-enhancing NFC RF chips and secure transaction chips in the same 4mm x 4mm mini-module. When market-leading boostedNFC® technology from STMicroelectronics is used to communicate with the reader during normal, non-telecom distance, small antenna wearable devices provide a superior user experience.

From fashion accessories to disposables, such as bracelets for event participants, this 2-in-1 module enables card merchants to quickly introduce wear-ready devices with superior functionality and design. STMicroelectronics also offers a powerful development ecosystem for this module, including RF tuning tools and pre-defined antenna configurations. The ST53G meets all relevant standards in the card industry, including the EMVCo® compliance standard, ISO / IEC-14443 NFC card emulation mode, and MIFARE® ticketing specifications.
The ST53G complements STMicroelectronics' family of SoC products that run the ready-to-use STPay smart card operating system and VISA / Mastercard / JCB-certified banking applications preinstalled on secure microcontrollers.
Laurent Degauque, director of marketing for Secure Microcontroller Products, said: "From disposable devices to fashion accessories, our new chip module gives consumers greater access to fast, easy and unobstructed bank cards by enabling secure transactions on wearable devices. Payment and sale of tickets, and we are already working with customers to develop new ST53G-based products and support these market-friendly use cases. "
The ST53G system package is available in a 4mm x 4mm WFBGA64 package and will begin shipping sample works today with production scheduled for the first quarter of 2018. For product details and value information, contact your local STMicroelectronics sales office.
More technical details:
Within the ST53G system package, the Secure Transaction Chip incorporates STMicroelectronics' market-proven ST31G480 high-performance smart card secure microcontroller based on the Arm® SC000 SecurCore® processor core. The security architecture includes the NESCRYPT coprocessor, which handles public-key encryption algorithms And hardware accelerators that perform AES and 3DES encryption algorithms; multiple tamper protection features, including proactive protection, environmental monitoring, a one-piece number (one chip comes with a unique serial number), and many other attack-defense features The software security features running on the SC000 core build a solid line of defense to protect the user's certificate.
The non-contact chip is the STS3922 RF enhancer, which maximizes the communication distance and omni-directional RF performance of the card emulation mode through Active Load Modulation (ALM) technology, making the wearable device easier to use and device-to-card reader position tolerances comparable to or even superior In the traditional non-connected smart card, even with a smaller antenna also has excellent performance. The ST53G helps optimize the final product cost because small antennas can be etched on a printed circuit board with virtually no additional cost. In some cases, the metal housing can act as part of the RF antenna function, but this design has a certain degree of difficulty.
In addition, techniques such as automatic power and gain control, configurable sensitivity and configurable signal / reader field phase contrast ensure consistent communication performance over different distances while improving interoperability with different types of readers and terminals Sex, including all kinds of bus cards. The STS3922 itself is a low-power RF chip that enables the ST53G system package to turn off the power at idle to maximize battery life.
The ST31G480 Security Unit has been certified to both the EMVCo and Common Criteria standards and the STS3922 RF chip complies with ISO / IEC 14443 and EMVCo Level 1 standards to ensure full interoperability with existing payment terminals and ticket sales devices.
In addition to RF tuning tools, STMicroelectronics offers Software Development Kit (SDK) for implementing chip card services on a variety of wearables architectures, as well as reference designs and expansion boards, as well as solutions that help simplify design and speed time-to-market Pre-certification services.
