Away across multiple electronics applications, the world's leading semiconductor supply commercial semiconductor (STMicroelectronics, referred to as ST; New York Stock Exchange Code: STM) Introduces fashion jewelry such as the most popular bracelet, watch or jewelry, etc. Semiconductor technology of contact transactions. ST53G system package solutions for STMicos STMS ST53G system packages are integrated with its market leading close communication (NFC) technology and security transaction chips in the same package.
As consumers are getting safe and securely using intelligent equipment, the card merchants intend to enter the non-contact wear equipment market with payment, sale ticket and access control, but it is difficult to achieve these in the size and cost of wear products. Function, because the traditional non-contact IC card consists of two independent devices of NFC RF chips and safety chips, requires more space, and is complex. In addition, the small size characteristics of the wear devices determine the small antennas whose communication performance can only be used.
The new product ST53G system package of Semiconductors overcomes these technical disorders, integrating miniaturized and performance-enhanced NFC radio frequency chips and security transaction chips within a small module of 4mm x 4mm. When communicating within a normal non-communication distance, the market-leading BOOSTEDNFCTM technology, which is semiconductor, the industry, to provide a small antenna wear device to provide a quality experience experience.
From fashion jewelry to disposable products, for example, the bracelet to the active participant, this two-in-one module allows card merchants to quickly launch functional and design unparalleled wear devices. STMicroe is also providing powerful development ecosystems for this module, including RF tuning tools and predefined antenna configurations. ST53G meets all relevant standards in the card industry, including EMVCOTM compatibility criteria, ISO / IEC-14443 NFC card simulation mode and MIFARE® ticketing technical specifications.
ST53G improves the system chip product line of STMicroelectronics, which can run the immediate STPAY smart card operating system and the Visa / MasterCard / JCB certified bank app preloaded on the security microcontroller.
Laurent Degauque, Director of Safety Microcontroller Product Department, said: "From one-time equipment to fashion jewelry, through security transactions on wearable devices, our new chip module makes consumers more opportunities to enjoy rapid and convenient, unimpeded bank cards Pay and check check service. We have developed ST53G-based new products in cooperation with our customers and support these market friendship. "
The ST53G system package uses 4mm × 4mm WFBGA64 packages, which starts supplying engineering samples, which plans to mass production in the first quarter of 2018. For more information on product details and value, please contact your local integral semiconductor sales office.
More technical details:
Inside the ST53G system package, the security transaction chip uses the ST31G480 high-performance smart card security microcontroller for the market inspection of STMicase, based on the ARM® SC000 SecurCore® processor core; the security architecture includes the NESCRYPT coprocessor for processing public key encryption algorithms. And implement the hardware accelerator of the AES and 3DES encryption algorithm; multiple tamper-proof protection features, including active protection, environmental monitoring, one (one chip comes with a unique serial number), and many other attack defense features, these protection functions Software security features running on the SC000 core build a stronger line of defense and protect users' certificate security.
Non-contact chip is the STS3922 RF booster, maximizing the communication distance of the card simulation mode with the active load modulation (ALM) technology to maximize radio frequency performance, so that wear equipment is better, and the equipment to the card reader is equally good. In traditional non-smart cards, there is also an excellent performance in a smaller antenna. ST53G helps optimize the final product cost, because small antennas can be etched on the printed circuit board, basically there is no additional cost. In some cases, the metal housing can act as part of the RF antenna, but this design has a certain difficulty.
In addition, technologies such as power and gain automatic control, configurable sensitivity and configurable signal / card reader magnetic field phase difference ensure that communication performance is consistent while different distances, while also improving interoperability with different types of card readers and terminals. Sex, including all kinds of bus cards. STS3922 itself is a low-power RF chip, and the security microcontroller wakes a dedicated output to allow the ST53G system package to close the power to maximize battery life.
The ST31G480 security unit has obtained two standard certifications for EMVCO and Common criteria, and the STS3922 RF chip conforms to ISO / IEC 14443 and EMVCO Level 1 standard to ensure complete interoperability with existing payment terminals and check-in equipment.
In addition to RF tuning tools, the STMicroelectronics also provides software development tool kits (SDK) for chip card services on different wear equipment architectures, as well as reference design and expansion boards, and also provide aid to simplify design and speeding products. Pre-certification service.
