Quoted foreign reports, due to the use of Intel B3 Stepping 6 series chipset motherboard is currently mass production, in the case of a large increase in demand, coupled with the impact of Japan's Kanto earthquake, NEC is currently the main USB 3.0 interface for the first generation of USB 3.0 Control chip shipments will face tightness, and there are already opportunities to become more serious in May. It is understood that NEC has lobbied customers to adopt second-generation controllers .
With the popularity of the USB 3.0 interface, the new motherboards currently available in the market have basically required USB 3.0 interfaces. According to NEC, due to the re-production of Intel B3 Stepping 6-series chipset motherboards, the demand for the first-generation uPD720200 USB 3.0 controllers has increased significantly, and therefore it is in a tight supply situation in the short term.
At the same time, some motherboard makers also pointed out that due to the impact of the power supply problem after the earthquake in Kanto in Japan, NEC's plants needed to be shut down. Under the influence of the production line, NEC's USB 3.0 controller may be out of stock in May. .
However, NEC also pointed out that currently the second-generation uPD720200A USB 3.0 controller is available in a stable manner. In order to reduce the shortage of the first-generation uPD720200, it has begun to lobby motherboard makers to adopt second-generation controllers, but the test will take one month. At the same time, the third-generation USB 3.0 controller is expected to begin mass production in September, so the supply of USB 3.0 controllers should not be a big problem.
