As consumers become more confident in using smart devices for secure transactions, card vendors intend to enter the market for contactless wearables with payment, ticketing and access control functions, but these are difficult to achieve in wearable products where size and cost are limited. Function, because the traditional contactless IC card is composed of two independent devices, an NFC RF chip and a security chip, which requires more space and is complicated in design. In addition, the small size of the wearable device determines that it can only use small antennas with limited communication capabilities.
ST's new ST53G system package overcomes these technical barriers by integrating miniaturized and performance-enhanced NFC RF chips and secure transaction chips in the same small 4mm x 4mm module. STMicroelectronics' industry-leading boostedNFCTM technology enables small antenna wearable devices to provide a superior user experience when communicating with readers over normal non-contact distances.
From fashion accessories to one-off products, such as wristbands for event participants, this two-in-one module allows cardholders to quickly introduce functional and well-designed wearables. STMicroelectronics also provides a powerful development ecosystem for this module, including RF tuning tools and predefined antenna configurations. The ST53G meets all relevant standards in the card industry, including EMVCoTM compatibility standards, ISO/IEC-14443 NFC card emulation mode and MIFARE® ticketing technology specifications.
ST53G complements ST's system-on-chip product line, which runs the ready-to-use STPay smart card operating system and VISA/Mastercard/JCB-certified banking applications pre-installed on secure microcontrollers.
Laurent Degauque, Director of Marketing for Secure Microcontrollers, said: "From disposable devices to fashion accessories, our new chip modules give consumers a chance to enjoy fast, easy-to-follow bank cards by enabling secure transactions on wearable devices. Payment and ticketing services. We are already working with our customers to develop new ST53G-based products and support these market-friendly use cases."
The ST53G system package is packaged in a 4mm × 4mm WFBGA64 package, and engineering samples will be available from now on. It is planned to be mass-produced in the first quarter of 2018. For product details and value information, please contact your local STMicroelectronics sales office.
More technical details:
Inside the ST53G system package, the secure transaction chip uses ST's market-proven ST31G480 high-performance smart card security microcontroller based on the Arm® SC000 SecurCore® processor core; the security architecture includes the NESCRYPT coprocessor for handling public key encryption algorithms And hardware accelerators that implement AES and 3DES encryption algorithms; multiple tamper-proof protection features, including active protection, environmental monitoring, one-number one (one chip comes with a unique serial number), and many other attack defense features, these protection functions The software security features running on the SC000 core build a strongest line of defense to protect the user's certificate security.
The non-connected chip is the STS3922 RF booster. The active load modulation (ALM) technology maximizes the communication distance and omnidirectional RF performance of the card emulation mode, making the wearable device more usable. The device-to-reader position tolerance is comparable or even better. For traditional non-connected smart cards, even with smaller antennas, there is excellent performance. The ST53G helps to optimize end product cost because small antennas can be etched on printed circuit boards with virtually no additional cost. In some cases, the metal casing can function as part of the RF antenna, but this design is somewhat difficult.
In addition, power and gain auto-control, configurable sensitivity and configurable signal/reader magnetic field phase difference ensure communication performance is consistent at different distances, while also enhancing interoperability with different types of readers and terminals. Sex, including all types of bus cards. The STS3922 itself is a low-power RF chip. The secure microcontroller wake-up dedicated output allows the ST53G system package to turn off the power at idle time, maximizing battery life.
The ST31G480 security unit has achieved two standards of EMVCo and Common Criteria. The STS3922 radio frequency chip complies with ISO/IEC 14443 and EMVCo Level 1 standards, ensuring full interoperability with existing payment terminals and ticket inspection equipment.
In addition to RF tuning tools, ST also provides software development kits (SDKs) for reference card implementations on different wearable device architectures, as well as reference designs and expansion boards, while also helping to simplify design and speed time-to-market. Pre-certification service.
DC Cable is the cable used for the products with DC (direct current) output like all AC/DC adapters including laptop Adapter , desktop adapter, wall plug adapter, Printer Adapter, and Linear Adapter and so on. The one end of dc cord is 2 or 3 open wires to connect with adapters or chargers, the other end of dc Power Cable is different dc jack, standard dc jacks for laptop adapter are 5.5*2.5, 5.5*2.1, 5.5*1.7, 4.8*1.7, 4.0*1.7, 3.5*1.35, , 3.0*1.0, 2.5*0.7, 2.0*0.6, 4.0*1.35, 6.3*3.0, 5.5*3.0 with pin, 7.4*5.0 with pin, 6.5*4.4 with pin, 4.5*3.0 with pin, 4 pin, 4 hole, 5 hole oval, 3 pin, 3 hole, etc, and standard dc jacks for tablet are 2.5*0.7, 3.0*1.0, 2.0*0.6, micro usb, and mini usb, etc.
Except dc jack, three main specifications are OD of cable, length of cable and materials specifications inside of cable. OD means outer diameter, it is normally 3.5mm for wall plug adapter, 4.0mm, 4.5mm, 5.0mm, 5.5mm for big power laptop adapter and other ac/dc adapter. Length is normally 1.2m, 1.5m, and 1.8m, also 2m, 3m, 5m are customized produce. The materials inside are pure copper, CCA ( copper and Aluminum) and CCS (copper and steel), pure copper is the best, CCA is second, CCS is the lowest, yidashun never uses CCS; And the thickness for the materials inside are normally 0.15mm2, 0.19mm2, 0.2mm2, 0.33mm2, 0.41mm2, 0.5mm2, 0.75mm2, 1mm2, 1.25mm2, 1.5mm2, 2mm2 and so on. Normally we use 0.15mm2 and 0.2mm2 for below 30W adapter, 0.41mm2 and 0.5mm2 for below 90W adapter, and 0.75mm2 and more thickness for above 90W adapter.
