UMC, Taiwan's foundry industry, recently said that its board of directors voted to close its 200-mm wafer factory in Japan to cut costs to cope with the current difficult macro-economic situation and the decline in customer demand situation.

"Because of the rapidly changing international economic climate and industry trends, Japanese customers demand recession, plus the 2011 East Japan earthquake disaster, unstable energy supply the semiconductor on downstream industries have been downsizing in response to cuts or plant closures," UMC (Hsinchu, Taiwan) in the documents submitted to the Taiwan Stock Exchange, said, "UMC Japan's operating costs can not effectively reduce the overall operating performance failed to achieve the desired goals for the integration of the business and improve the manufacturing resource use efficiency, reduce operating costs, Lianhua electronic board resolutions end wafer manufacturing operations in Japan. "

UMC said in Tateyama, Chiba, Japan, Japanese wafer manufacturing operations after the completion of the final orders will abort. The company said, the dissolution and liquidation of the UMC Japan at a future time.

Made part of the shares of Nippon Steel Semiconductor UMC in 1998 and responsible for the operation, later renamed as UMC Japan; UMC UMC Japan tender offer all outstanding shares.

UMC through other plants in the future will continue to be an adequate supply of foundry needs of local customers in Japan. These factories are almost all located in Taiwan.

UMC UMC Japan 200 mm wafer monthly production capacity of about 20,000, and ending on June 30 this year, the total assets of 16.8 billion yen (U.S. $ 212.2 million) and liabilities of 2.8 billion yen (U.S. $ 34.4 million dollars).

UMC UMC Japan in the first half revenue of 3.7 billion yen (U.S. $ 46.8 million), a net loss of 1.6 billion yen (U.S. $ 20.2 million).

UMC said last month, will sell 10% of the shares of one or more strategic partners. UMC foundry field long second ranked TSMC after. According to market research firm IC Insights Inc., the UMC foundry operating income rankings this year may fall to third, came in TSMC and Globalfoundries Inc. Behind.

Austriamicrosystems is a leading global provider of high-performance analog IC designers and manufacturers for consumer and communications, industrial, medical, automotive applications, industry services, the company has released a new intelligent LED driver chip AS3661 can control multiple 9 LED the fine indicator light for mobile devices, independent of the power consumption of the baseband processor.

The new consumer electronics devices, including 3G and LTE modem, USB memory stick, game controllers and headphones useful indicator can be used to improve the user interface of these devices, and the lighting effects of the high quality and low power consumption are these devices necessary.

AS3661 support a simple command-based programming. Three independent program execution engine to form three independent programmable LED group. This means that LED driver can be grouped according to function, for example, the first group of drivers can be used to control the keyboard lighting, used to generate a second set of "interesting light efficiency" (control a variety of LED light output), the three groups can be used to control instruction LED.

Each program execution engine can be driven 1-9 LED. AS3661 contains a total of nine LED channels, each channel drive current up to 25mA. Each of the nine channel has a dedicated 12-bit PWM controller, smooth color conversion and achieve linear fade-in fade-out effect on the number and ratio.

Program execution engine instruction is stored in the program memory, and a total capacity of 96 instructions, the user can be assigned a maximum 1.5kbit memory to the program execution engine needed. AS3661 smart LED driver chip with an I2C control interface (supports 4 I2C device address pin by chip select). The interface of the device is a flexible general-purpose output (GPO) can be used as the output of the control of other devices. INT output can notify the central processor at the end of the program execution. The device also provides a trigger input interface, in order to achieve synchronization between multiple AS3661.

To optimize battery life, the AS3661 design includes a variety of power-saving features. Each channel is less than 50mV (output current of 10mA) differential pressure operation, high efficiency 150mA charge pump powered by 1:1 and 1:1.5 mode automatically switches. In addition, when the LED is no output can automatically enter a power saving mode, when consuming only 10μA of current (typical value).

Senior Marketing Manager of austriamicrosystems optoelectronic products said Ronald Tingl,: austriamicrosystems leap innovation impressive new features for mobile phones and other consumer electronics devices market. AS3661 intelligent lighting driver chip allows system designers to provide the user with the functionality of the more eye-catching effects and had never experienced before. new portable devices really bring vivid colors. AS3661 austriamicrosystems lighting products series broaden the products including flash backlight dot matrix driver chips and powerful lighting management unit. "

AS3661 rich austriamicrosystems existing smart lighting driver IC products series include:

Enhanced version of AS3665, AS3661 can also drive the nine LED differs in that, the product having an audio sync pattern, the LED lights can be based on the brightness and color of the input audio transform.
AS3668, a simple intelligent 4-channel RGBW driver chips.
