The third-generation universal serial bus (USB 3.0) will be a big hit in the smartphone market. With the advanced nanometer (nm) process, the unit price of USB 3.0 chips has approached USB 2.0, which not only accelerates the expansion of USB 3.0 market penetration in personal computers (PCs), PC peripheral devices and servers, but also is expected to accelerate the replacement of USB 2.0 to become a smart The mainstream transmission interface of mobile phones.
Chen Yuzuo, manager of the third application technology department of Renesas Electronics in Taiwan, said that at this stage, there is almost no price difference between USB 3.0 chips and USB 2.0, which will accelerate the rapid expansion of USB 3.0 penetration in the mobile device market.
Chen Yuzuo, manager of the third application technology department of Renesas Electronics in Taiwan, said that with the 90-nanometer process, the company's two-port USB 3.0 chip price is only 1.5 to 1.7 US dollars, and the four-port USB 3.0 chip costs about 2 US dollars; compared with Next, the unit price of Renesas ’three-port USB 2.0 chip produced using a 0.25-micron process is US $ 1.5-1.7, which shows that the prices of USB 3.0 and USB 2.0 chips are not far behind.
Xu Jinsong, deputy general manager of Weifeng Electronic Product Center, also pointed out that since 2010, more new entrants entered the USB 3.0 market, and the price war has become more intense. In addition, USB 3.0 chip manufacturers are competing to introduce 0.13 microns (μm), 90 Nano and even 65 nanometer processes are put into production, so the price of USB 3.0 chips has accelerated. Before 2010, the USB 3.0 chip used in the host and the hub was priced at US $ 3 to US $ 5, and the unit price of the USB 3.0 chip used in the periphery was US $ 3 to US $ 4. Currently, the host, hub and peripherals are used USB 3.0 chip prices have been lower than 2 US dollars.
As the price gap with USB 2.0 chips is getting smaller and smaller, the penetration rate of USB 3.0 in the PC market has rapidly increased. Chen Yuzuo predicts that, unlike 2012, where the application scope is limited to mid- to high-end and a few low-end personal computers (PCs), USB 3.0 penetration in the PC market is expected to approach 100% in 2013.
In addition to the sharp decline in the price of USB 3.0 chips, USB 3.0-integrated processors have also been released, which will help USB 3.0 enter a large number of tablet devices this year and enter the smartphone market in 2014. Xu Jinsong mentioned that the power consumption of USB 3.0 is lower than that of USB 2.0, and the price of USB 2.0 chips is getting closer, which will help it to attack the market in the market of tablet devices and smartphones, especially driven by the PCization of tablet devices. It is expected that tablet devices will introduce USB 3.0 functionality faster than smart phones.
