STMicroelectronics ST Introduces High-Performance NFC Technology for Secure Contactless Payment and Internet of Things

2024-09-19 13:16:13

STMicroelectronics unveiled a new generation of NFC chips for contactless payment and data exchange with three new products including a ST21NFCD NFC controller and two ST54 system-in-package (SiP) families. The ST21NFCD incorporates the market-proven boost technology recently acquired by STMicroelectronics, while the ST54 system-on-package integrates NFC controllers and the latest security unit technology from STMicroelectronics.

Active Load Modulation, a highlight of the ST21NFCD chip, ensures faster, smoother transaction processing and longer data exchange distances, giving mobile and wearable devices and IoT hardware a better user experience. The new controller supports card mode, read and write mode and peer-to-peer communication mode, built-in embedded flash memory, support the overall firmware upgrade. The ST21NFCD supports the NFC Forum's NCI 2.0 specification, which simplifies the development of NFC tag interaction software, supports data batch and automatic interaction, and minimizes communication overhead. The chip also complies with the NFC Forum type 1-5 tag standard, the ISO / IEC 18092 NFC Interface and Protocol (NFCIP), and payment standards including the latest version of EMVCo, as well as the Global Certification Forum (GCF) and PTCRB [1] handsets Integrated pre-certification, so that the phone can read the MIFARE ClassicTM encryption tag data.

On-chip power management and battery voltage monitoring help minimize the impact of NFC on the life of a host system such as a mobile phone. Extremely high RF sensitivity allows designers to use micro-antennas; alternative to external crystal instead of crystal; DC / DC booster options for high output power; each option helps save device cost and circuitry Board space.

STMicroelectronics latest ST54 system-level package ST54F and ST54H two products, integrated ST21NFCD NFC controller and embedded security unit (eSE). The Embedded Security Unit is an ST33 Secure Microcontroller that has passed the most current level of data security certification including the Common Criteria EAL5 + and EMVCo payment standards for data replication and cracking on a compact, easy-to-use chip Protection based on the market-proven ARM® SecurCore® Sc300® processor core with secure operating system running Java Card ™ and GlobalPlatform®.

ST54F integrated ST21NFCD controller and the most widely used on-chip Flash memory up to 1.28MB ST33G1M2 safety unit, and ST54H built-in technology more advanced on-chip flash memory capacity of up to 2MB of ST33J2M0 security unit, computing performance doubled ST33G1M2, to connect to service providers New digital security application.

The ST21NFCD and the new ST54 system-in-package are now in production in a 4mm x 4mm x 0.8mm 64-lead WFBGA package.

Commercial Treadmill

Commercial treadmills are mainly used in professional places with high usage such as gyms, clubs, and star rated hotels, with running belts generally between 45-65. Unlike home treadmills, commercial treadmills use an AC motor+frequency converter drive method, which can run for longer periods of time without causing the motor to burn out.

Is it worth buying a commercial gym treadmill?

Spending more upfront on commercial treadmills offers several benefits: Withstands high traffic and hours of use without breaking down. Advanced features better suit the gym/training environment. Covered by warranty when used properly.

What's the difference between a commercial treadmill and a regular treadmill?

Commercial electric treadmills are designed for heavy usage and are built with high-grade materials, making them more durable than home running machines. On the other hand, home treadmills are suitable for individuals who have limited time to exercise or prefer to workout in the comfort of their own homes
