About Dallas and Elan:

Founded in 1994, ELAN Microelectronics Corporation is an IC design house engaging in the R&D of integrated circuit and touchpad module solutions. The company is headquartered in Taiwan Hsinchu Science Park with touchpad module factory in Chung Ho City, Taipei County. Through years of development, it has branch offices and customer service centers all over the world such as USA, Shenzhen (China), Shanghai, and Hong Kong, etc. Besides, the company has been listed in the Taiwan Stock Exchange since September 2001. ELAN’s products can be summarized into the following categories: microcontrollers, touch sensor ICs, telecommunication ICs, PC peripheral ICs, audio/video ICs and capacitive touchpads. The typical applications include mobile phones, notebooks, home appliances, toys & gaming, calculators & education devices, handheld devices, PC peripherals, telecommunications and smart remote controls. ELAN has been certified by the quality management system ISO 9001:2000. ELAN has its core technology focusing on Capacitive Touchpad. Along with the release of the Apple iPhone in mid-2007 and the introduction of iPod Touch, MacBook Air, Windows 7.0, the Multi-Finger touch interface has rapidly become to be the trend of Human-Machine Interface (HMI) development. ELAN’s Capacitive Touchpad products include Illuminative Touchpad, Transparent Touchpad, and Virtual Keypad with Dome Touchpad. Besides, CMOS Sensor with Pattern Recognition is ELAN’s second core technology. It is an integration of ELAN’s MCU and DSP for digital audio/home appliance applications and pattern recognition algorithm. The technology is used in the development of optical mouse, interactive game console, interactive TV, computer games, optical identification device, etc. ELAN is always persisting on the investment in the R&D of new products. ELAN has earned an extensive number intellectual property (IP) patents. ELAN R&D has received several gold and silver medals in the annual “Taiwan National Best Invention Award” sponsored by the ROC Ministry of Economic Affairs. It also received many “R&D Accomplishment Awards” from the Hsinchu Science Park Administration. The company is also listed as one of the “Best Under a Billion 200 Companies” worldwide by Forbes Global Magazine.

As an expertise in Smart Human-Machine Interface applications development, ELAN has its core technology devoted in Capacitive Touchpad. Since the release of the Apple iPhone in mid-2007, followed by the introduction of iPod Touch, MacBook Air, and the up coming release of Windows 7.0, the Multi-Finger touch interface has fast grown to be the focus and trend of Human-Machine Interface (HMI) development. As of this date, ELAN’s Capacitive Touchpad products include Illuminative Touchpad, Transparent Touchpad, and Virtual Keypad with Dome Touchpad. All these products provide Multi-Finger touch applications for clicking, zooming, scrolling, cursor control, and other gesture mode functions. The Multi-Finger touch solutions from ELAN are smarter, intuitive, user-friendly, reliable, and are fast gaining popularity with reputable consumer electronic products, while the solution is becoming a market trend’s smart choice.

Dallas Semiconductor was founded in 1984 as a designer and manufacturer of semiconductors and chip-based subsystems. Dallas Semiconductor quickly established its innovation and technical leadership in developing a wide variety of high-performance products, including 1-Wire?, iButton?, microcontroller (MCU), timekeeping, thermal management, and communications devices.

Dallas Semiconductor, acquired by Maxim Integrated Products in 2001, was a company that designed and manufactured analog, digital, and mixed-signal semiconductors (integrated circuits, or ICs). Its specialties included communications products (including T/E and Ethernet products), microcontrollers, battery management, thermal sensing and thermal management, non-volatile random-access memory, microprocessor supervisors, delay lines, silicon oscillators, digital potentiometers, real-time clocks, temperature-compensated crystal oscillators (TCXOs), iButton, and 1-Wire products.

The company, based in Dallas, Texas, was founded in 1984 and purchased by Maxim Integrated Products in 2001. Both the Maxim and Dallas Semiconductor brands were actively used until 2007. Since then, the Maxim name has been used for all new products, though the Dallas Semiconductor brand has been retained for some older products, which can be identified by “DS” at the beginning of their part numbers.

The DS2432 combines 1024 bits of EEPROM, a 64-bit secret, an 8-byte register/control page with up to five user read/write bytes, a 512-bit SHA-1 engine, and a fully-featured 1-Wire interface in a single chip.
