NFC is not a new technology, its origins should start from 2003. This is a compatible wireless communication technology between Philips and Sony based on contactless card technology. The project, which was completed by Philips and Sony engineers for three months, publicly announced the results. It was compatible with the current ISO14443. The wireless communication technology of the contact card protocol is named NFC.
After winning the Amers NFC business for 100 million US dollars, ST is the world's leading first-generation model in the NFC field of readers, controllers and security modules. At the recent Munich Electronics Show, ST brought LED driver with M24LR04/16 dynamic NFC tag, NFC temperature sensor, NFC fast Bluetooth pairing headset, NFC smart lock and many other solutions.
ST NFC product line manager Yang Dawen said that ST's M24LR series is a dynamic tag chip with integrated I2C interface and NFC RF front-end, with energy harvesting output power up to 10mW, and user-programmable digital output and password protection. Supporting 105 degrees operating temperature, the device is widely used in dynamic labels in the fields of industrial, security, logistics, and consumer electronics. Recently, ST introduced the new ST25DV series products in addition to supporting all the features of the above M24LR, and more specifically support the transparent channel function, its built-in 256Byte RAM space, can provide high-speed data exchange through I2C and NFC. Therefore, it can be widely applied in the fields of programmable setting and configuration of industrial equipment, data collection and management of logistics tracking, data interaction and management of production processes, and data interaction of health medical products, providing customers with a better experience. The ST25DV series of chips also improve energy harvesting performance and provide more power, which is further expanded in green energy, battery-free, fireproof, waterproof and corrosion-resistant full-sealing applications.
As a semiconductor manufacturer with a fab, ST's products are used in five major areas of MEMS manufacturing and sensors, vehicles, energy, microcontrollers, and consumer electronics. The NFC chip is part of the microcontroller business unit.
Since the processor of the mobile device is mostly developed based on the architecture of the ARM, in order to increase the versatility of the product and facilitate the development and use of the terminal industry, STMicroelectronics cooperates with ARM based on its processor architecture. Developed up to 450 kinds of MCUs, including products from high computing speed to low computing speed. It is integrated with MCU and NFC readers and controllers, and is equipped with NFC applications in different terminal types. Let the industry make the best choice from the application side and price.
In addition, the development of product specifications of NFC chip manufacturers can be summarized into several common features: chip miniaturization, power saving, multi-communication standard compatibility, high transmission speed, and the development of various international security certifications. The main reasons are as follows.
1. The trend of mobile payment, NFC controller chip on smart phone is mainly used in the payment field to develop continuously. At the same time, the smart POS machine market which has been gradually developed in recent years has also attracted more manufacturers to invest. ST's ST25R3911B NFC read/write chip provides excellent performance. RF performance and full EMVCo L1 firmware support enable customers to pass EMVCO and PBOC certification tests with minimal effort in the shortest amount of time. In addition, ST's smallest 3*2.8mm ST25R3912 NFC read/write chip in the industry allows customers to lay out boards in a limited space, thus miniaturizing the product.
2. Under the rise of smart networking, NFC technology as an effective means of wireless connection authentication enables Bluetooth, WiFi, Zigbee, etc. to complete connection authentication at the touch of an instant. In addition, NFC as a technology of touch and transmission, has the advantages that other wireless technologies do not have the advantages of small data volume interaction and instant completion, and can be widely applied in the field of light object networking.
3. In order to increase the versatility of the NFC chip and make it easy for terminal operators to adopt, the NFC tag chip, dynamic tag chip and reader chip introduced by ST today also follow the NFC Forum communication standard, thereby making NFC compatibility better.
