In view of the popularization of Internet of Things, the progress of wireless transmission technology is an important key. It is noteworthy that near field communication has played an increasingly important role in a variety of wireless transmission technologies. According to a research report by IHS, NFC smart phone sales will reach 2.2 billion by 2020. In addition, devices such as PCs and peripherals, network devices, smart homes, automotive devices, healthcare, smart meters and industrial automation will all be available NFC will be built more widely.
However, in recent years, many innovations in technologies and products have revolved around the theme of "Internet of Things (IoT)." The emergence of Internet-related applications is full of unlimited imagination, driving up the huge market demand and prompting the industry to continue To invest in smart cities, smart home, smart life, identity recognition, remote medical applications. Internet of Things, our food and clothing daily necessities such as living, working environment and mode of operation, leisure and entertainment will have a major change.
According to the information released by international research institute Gartner in 2015, it is estimated that there will be more than 26 billion network-connected devices in 2020, and subsequent derivative business opportunities are expected to reach as high as trillion U.S. dollars. The McKinsey Global Institute also predicts that by 2025, IoT-related applications will generate up to 11 trillion U.S. dollars (361 billion U.S. dollars) in the global economy.

STMicroelectronics plays a huge role in pushing hands on opportunities
NFC technology has a long history, it is a kind of short-range high-frequency wireless communication technology, allowing non-contact point-to-point data transmission and data exchange between electronic devices. NFC operates at a frequency of 13.56MHz within a distance of 10cm and has a transmission speed of 106Kbit / s, 212Kbit / s or 424Kbit / s.
At present, NFC has passed the ISO / IECIS18092 international standard, EMCA-340 standard and ETSITS102190 standard. NFC uses both active and passive read mode. In practice, NFC emits a short-range signal that triggers an action. When a user touches two devices with each other, such as a smart phone and a speaker, NFC immediately connects the two with NFC-free and password-free benefits , Use a lot more convenient.
In order to help Taiwanese partners to grasp the trend of Internet of Things, the semiconductor industry leader STMicroelectronics (ST), in particular, and Ye Ye Technology jointly held a few days ago "Internet of Things NFC / RFID key technologies and new trends in application seminars," invited a number of experts Share emerging trends in the Internet of Things, and introduce product profiles such as NFC / RFID, analog sensing components, microcontrollers (MCUs), and smart security. STMicroelectronics demonstrated a variety of innovative products and new applications on site, and exchanged warmly with guests on the scene to share business opportunities in the smart industry up to trillion dollars.
Deliverable data and energy RFID unique
The first seminar to be shared was STMicroelectronics product marketing manager Huang Yiyi. He pointed out that everything can be built-in NFC with the example of mobile phones, tablets, hats, notebooks, manuals, keys, badges, and watches worn by individuals. Connect with the outside world in a quick and easy way. Huang Yiyi and emphasized that RFID is the only wireless technology that can transmit data and energy, so the range of applications will also be more expanded.
Huang Yi is quite optimistic about the NFC-based RFID technology in the field of Internet of Things possibilities. In particular, Apple joined NFCForum in the previous year (2015). Its latest mobile phone has been enabled with NFC capabilities and is expected to greatly boost the popularity of NFC. STMicroelectronics spares no effort in promoting NFC. In addition to being a key member of the NFC Forum, STMicroelectronics has also released related products and solutions.
Among them, ST has introduced NFC tags using non-volatile memory - erasable rewritable read only memory (EEPROM), compared to other vendors' products, ST's NFC tag data retention period of up to 200 years, Is 20 times the industry standard, erase the number of times over 1 million times, is 10 times the industry standard. Operating temperature range -40 ° C ~ 85 ° C, to ensure the label in the worst working conditions still maintain perfect read-write performance and durability.
ST's ST25TA series of products is the use of EEPROM, memory capacity from 2Kbit ~ 64Kbit, covering all existing market demand. The EEPROM memory block directly supports NDEF format for storing NFC data. ST is the world's largest supplier of EEPROM technology and EEPROM memory.
On the whole, ST's NFC tag chip offers the broadest memory range, the longest data retention period, the most repetitive writing times and the strongest data protection capability in the market. Its dynamic NFC tag can be linked with the I2C interface MCU, which can be used in the fields of consumer electronics, computer peripherals, home appliances, industrial automation, and health care products, for various electronic products in the Internet of Things, data access without power and data transmission with smart phones.
Micro Ferrite NFC tags using ST25 chip
It is worth mentioning that the Head of Huawei Technologies (SAG), which works with ST to provide high-performance mini-NFC tag solutions for IoT applications, also went to the field to share solutions. Is a global leader in RFID tagging and recently announced a NFC FerriteTag with STMicroelectronics ST25 Internet of Things (IoT) NFC tag chip for IoT data transmission.
The ferrite NFC tag with lightweight, slim and so on, the solder joints can be soldered directly to the printed circuit board surface, in the production line surface mount. In addition, ferrite NFC tags with anti-metal interference properties that work well even on metal products make them ideal for consumer electronics, wearable devices, and smart fitness medical products Internet of Things (IoT) data transfer . Compact and lightweight is essential for wearable products, the new Ferrite NFC specification also well meet the needs of lightweight and slim wearable products.
In addition to its compact size and slimness (4.9x3.0x2.5mm), this embedded ferrite NFC tag offers outstanding RF performance thanks to the most advanced STMicroelectronics support for NDEF (NFC Data Interchange Format ST25TA02KNFCForumType4 tag chip for information.
No need to use any specialized application software, Android NFC mobile phone can directly read and write NDEF data. In addition to supporting NDEF format, ST25TA02K also built-in 20-bit counter and 128-bit password encryption mechanism to protect the 2KbitEEPROM memory read and write operations.
Dynamic NFC tag built-in EEPROM
In order to give full play to ST's innovative "Dynamic NFC Labeling" function, Wu Xiangmin, a senior technical marketing engineer at STMicroelectronics, described the design focus of the DynamicNFC antenna. He pointed out that its location must be as close as possible to the NFC antenna location, preferably within a few millimeters, as the addition of any line may change the antenna's characteristics and require readjustment.
ST introduced "dynamic NFC tag memory" M24SR series, contains three important module chip, namely non-volatile memory (NVM), is an electronic memory will not be lost even if the power-down data; wired interface Industry standard I2C interface) to communicate with the host controller, operating at up to 1MHz, ensuring fast data transfer between the phone and the target device.
The third part is a wireless interface for communicating with other wireless devices. The wireless interface is completely compatible with the ISO14443-A communication protocol and has a data rate of up to 106kbps. Overall, the EEPROM in the M24SR chip eliminates the need for an external EEPROM, helping to reduce the overall module size and shorten the product development cycle, which is why it is favored by the industry.
32-bit microcontrollers are expected to become the core of connected devices
