Fudan Microelectronics launches UHF RFID overall solution, highly suitable for passive IoT application scenarios

Shanghai, August 30, 2022 - Shanghai Fudan Microelectronics Group Co., Ltd. announced today the launch of the ultra-high frequency FM13UF series tag chips and FM13RD1616 series reader chips , which have ultra-reliable and fast data writing and reading functions, can effectively improve the success rate of tag inventory, and significantly expand the tag reading distance. It is highly suitable for passive Internet of Things 2.0 and 3.0 application scenarios.

Xu Wanpeng, marketing director of Fudan Microelectronics Security and Identification Products Division, said that UHF (ultra-high frequency) RFID has a higher transmission rate than other frequency bands and can read a large number of electronic tags in a short time. It is very suitable for large-scale application scenarios and has obvious benefits for improving supply chain management efficiency. The report predicts that driven by related fields, the global estimated shipment volume of UHF RFID tags will reach 40 billion in 2024, and the domestic application volume of UHF RFID tags alone will reach 11.5 billion.

"With the rapid popularization of UHF RFID in a large number of application fields such as express logistics, supermarket retail, shoes and clothing, books and archives, airline baggage, smart transportation, and smart manufacturing, its market demand will also increase year by year." At the press conference, Wang Lei, product manager of Fudan Microelectronics, said, "We will exhibit FM13UF series tag chips and FM13RD1616 series reader chips at the IOTE International Internet of Things Exhibition to demonstrate our UHF RFID overall solution to customers on site."

UHF tag chip FM13UF series

Fudan Microelectronics has launched three EPC-compliant tag chips, namely UF0051E, UF011E and UF011X. In terms of capacity and function, they are comparable to the mainstream foreign chip products on the market. They have the characteristics of long reading and writing distance, strong anti-interference ability, high data reliability and high inventory success rate.

● Long reading and writing distance: It has a high-efficiency rectification circuit design, as well as a low-power digital-analog and memory circuit design, which greatly optimizes the chip's reading and writing performance, and has industry-leading read sensitivity (up to -24.2dBm) and write sensitivity (up to -23dBm).

● Strong anti-interference ability: It adopts an effective multi-tag anti-collision mechanism, can adapt to multiple readers and writers, and work in a high-density tag environment.

● High data reliability: With ultra-reliable data reading function, it can effectively avoid sending back erroneous EPC, TID or User area data. With fast data writing function, it can significantly improve the writing efficiency and ensure the reliability of written data.

● High inventory success rate: The innovative FDT technology, combined with the FM13RD1616 series reader chip, can effectively improve the tag inventory success rate and significantly expand the tag reading distance, making UHF RFID technology more suitable for passive Internet of Things application scenarios.

UHF reader chip RD1616 series

Fudan Microelectronics also simultaneously launched two UHF reader chips, RD1616E and RD1616G, which comply with the EPC and GB protocols. Their functions and performance are comparable to the mainstream foreign reader chip products on the market. They have industry-leading receiving sensitivity and can be used with Fudan Microelectronics' own MCU chip products to provide overall chip solutions. When used with the company's own FPGA and PSOC chip products and self-developed artificial intelligence (AI) algorithms, they can significantly improve the performance and scenario adaptation capabilities of UHF readers.

● Ultra-high read and write performance: With high-performance RF architecture and excellent core algorithms, it can quickly capture tag signals and write tag information to achieve better read and write effects. It supports wide-range reading of large quantities of tags and provides higher read and write reliability and stability in challenging environments.

● Ease of development: Combined with the company's own MCU chip products, it can provide an overall chip solution and significantly lower the development threshold.

● High sensitivity: It has the industry-leading receiving sensitivity, supports higher transmission power, and has the characteristics of low spurious and low phase noise.

● Innovation: Thanks to the innovatively designed FDT (FIND Tag) technology, users can use the FM13UF tag chip and FM13RD1616 reader chip in combination, which can effectively improve the success rate of tag inventory, significantly expand the tag reading distance, and make ultra-high frequency RFID technology more suitable for passive Internet of Things application scenarios.

At the end of the conference, Cao Yanyan, chief researcher of the Institute of Internet of Things Technology and Applications of China Mobile Research Institute, shared a keynote speech entitled "Passive Internet of Things, Opening a New Era of Internet of Everything". Cao Yanyan said that the evolution path of the overall passive Internet of Things can be divided into three typical stages: single-point passive 1.0, networking passive 2.0 and cellular passive 3.0. UHF passive Internet of Things technology has application advantages such as low cost, zero power consumption, maintenance-free and easy deployment. These technical advantages will better enable applications in retail, warehousing, logistics and other fields, and will continue to expand new fields, and join hands with the industry to enter a new era of Internet of Everything as soon as possible.

Relying on its independently developed radio frequency, memory and security anti-attack technologies, Fudan Microelectronics has now formed a series of chips including ultra-high frequency RFID tags and reader chips, high-frequency logic encryption card chips, NFC tag chips, NFC channel chips, and sensors combined with RFID technology. It is one of the suppliers with the most complete range of RFID chip products in China. Its products are widely used in identity recognition, offline counterfeiting detection, small-amount payments, smart homes, electronic price tags, anti-counterfeiting traceability, book management, supermarket retail, game entertainment, cold chain logistics and other fields.
