In the current smart hardware, in addition to consumer electronics such as smart phones and tablets, there are other types of products such as audio, camera, and home appliances. In general, most of the smart hardware survives with two main parts: input and output. Input refers to the input of big data, cloud data or real-time data, including image data, real-time data, historical data, etc. The output refers to the input data is transformed into valid data through hardware transformation and exported, and finally acts on people. In the simplest example, big data and cloud history data enter the earphone, and the innermost judgment of the earphone determines the most suitable sound size, the recipient's favorite tone, etc., and transmits it to the receiver's ear wirelessly. The above is the complete input and output. section. Here, the hardware level needs to complete the following steps: big data sharing and wireless data transmission, when it comes to real-time data generation, it will also involve NFC payment, but need to ensure that the intelligent hardware works in real time, but also lacks wireless charging. For example, in the case of the most used mobile phone, the most desirable state of the consumer is that no matter what time, the data can be transmitted without interference and quickly, while enjoying the data directly.
Big data transmission
Transfer Jet technology is the latest big data transmission technology, which uses Near Field Communication (NFC) combined with UWB (Ultra-Wide Band) speed (560Mbps). Transfer Jet is different from current general wireless transmission technology. No need for complicated connection settings for transmission, no wireless network access point, just transfer the products carrying Transfer Jet together and then transfer data, which makes two devices (such as mobile phones) , digital cameras, digital video cameras, TVs, game consoles or printers) can quickly share big data (photos, videos, videos, etc.). Transfer Jet is a kind of NFC technology. In order to improve the security of data transmission, only about 3cm of effective transmission (or touch) range is required, so that others cannot interfere or copy during the data transmission. Different from traditional NFC, NFC prefers slow transmission applications, mainly for user authorization or e-commerce payment. Transfer Jet combines UWB to achieve high-speed transmission, allowing for larger file capacity transmission. Users can share large amounts of content such as music and movies. For high speed, Figure 1 shows the comparison of the transfer speed of the current Transfer Jet technology. It can be clearly seen from the figure that the transmission speed of this technology is nearly 10 times that of the current Wi-Fi technology transmission, which is close to the Bluetooth transmission technology. 100 times, nearly 1,000 times that of NFC transmission technology.
Figure 1: Comparison of Transfer Jet.
For some intelligent hardware, most of them are currently using Wi-Fi for real-time transmission, but for special situations, such as fast transmission of large-capacity data such as movies, music, photos, videos, etc., Transfer Jet is a very good choice. And compared to Wi-Fi, Transfer Jet is not subject to radio interference, and will not cause a drop in transmission speed. Since the required distance is close (about 3 cm), the one-to-one communication and the docking time is 0.1 s, even if many people use it at the same time, the transmission speed does not decrease due to radio interference. Toshiba Semiconductor's TC35420AXLG product is an integrated chip that will be mainly used in SDIO interfaces such as smartphones and tablets. The chip integrates a small module "TJM35420XLQ" with filters and high-frequency components, a USB terminal-connected product "TJM35420UX", and a microUSB terminal-connected product "TJM35420MU". The IC device integrates the functions of the Transfer Jet function, namely wireless, signal processing, host interface and memory interface, on a single chip by using an RF-CMOS process, which is truly highly integrated.
In addition to being able to be used between friends and relatives, Toshiba Semiconductor's Transfer Jet can be directly commercialized. No need to initialize the settings, you can exchange instant information and content between friends and family, simple touch between smart phones can be achieved; it can also be used for offline sales of multimedia products, download through Transfer Jet, NFC Payment, for example, the sales office of digital products can directly buy the multimedia products that they want by using mobile phones in the sales hall without the network; local data transmission between IT devices, no need to connect data lines and operations Complex settings enable seamless transfer between multiple devices. At the same time, this technology is also an excellent marketing technique for O2O (Online to Offline). Smartphones touch each other, and information and content recommendations can be displayed on friends. In mobile phones, this way can promote the latest magazines, books and movies.
Wireless charging
For an excellent user experience, wireless charging is indispensable throughout the entire process, eliminating the need for cumbersome USB and charging lines and meeting the needs of consumers to further simplify their operations. Wireless charging technology can not only be used in consumer electronics, from the terminal to the manufacturing, but everywhere is filled with the shadow of wireless charging. Toshiba Semiconductor's wireless charging system also meets the wireless power requirements of these terminals, from AC adapters to the power-supply system to the power-receiving system to the battery management chip and finally to the battery, based on contact charging or contactless charging, while It is also important to reduce system energy consumption as much as possible.
So far, the wireless charging schemes on the market have been mixed. Take the LG WPC-300 chip as an example. The experimental environment is unified with the chip as the transmitting end, respectively using Toshiba Semiconductor's wireless charging receiving terminal TC7763WBG products and Company A products (original products). comparing. As can be seen from Figure 2, Company A's products have a maximum efficiency of 64%, while Toshiba Semiconductor's maximum efficiency is 68%. The 4% efficiency difference here is quite obvious at the receiving end.
