New Touch Controllers Provide Ultra-Low Power Consumption and Faster Time-to-Market
May 18, 2010
SAN JOSE, Calif., May 18, 2010 – IDT® (Integrated Device Technology, Inc.; NASDAQ: IDTI), a leading provider of essential mixed signal semiconductor solutions that enrich the digital media experience, today announced the newest members of the IDT PureTouch® family of capacitive touch devices. Targeting low-channel consumer, white goods and portable devices, the PureTouch technology can be implemented through button, slider and scroll options. By incorporating lower power consumption as well as new features, including advanced proximity sense capability and power-on touch detection, the latest controllers help designers improve product differentiation and time-to-market with easy customization and simple system design for those devices requiring eight or fewer buttons.
Offering increased functionality for IDT customers, the LDS6200 family is capable of detecting up to eight simultaneous touches and includes built-in proximity sensing, which allows activation of features such as backlighting and wake up prior to the actual touch contact. Moreover, IDT has also incorporated power-on touch detection into this new family to solve the problem of end devices not recognizing existing touches during power on. This feature allows the end application to recognize touch events already present at power on — a critical capability enabling many consumer devices to enter diagnostic modes.
“Consumers are demanding touch interfaces in a wide variety of devices because of their ease of use, intuitive interface and stylish look. This future growth opportunity makes it an exciting industry to be part of,” said Alvin Wong, general manager of the IDT Advanced User Interface group. “The highly integrated IDT PureTouch family of devices reduces component count, cuts design complexity and cost, and enables faster product development. The additional features of our latest touch controllers demonstrate the IDT commitment to enhancing the digital media experience through continued innovation.”
Building on other members of the PureTouch family, the LDS6200 series follows the IDT Power Smart initiative and is further optimized for ultra-low power consumption. The family enables power-efficient continuous scan of buttons without sleep modes, making the LDS6200 an ideal solution for battery-driven portable applications. In continuous scan mode, the LDS6200 consumes only 100uW, which is 20 percent lower than the current product family. With wide voltage range support (1.8V to 5.5V DC), no external voltage converter is required for non-portable applications.
The IDT LDS6200 family of devices offers support for I2C — the most common interface for applications ranging from white goods to mobile devices. Furthermore, the new members of the PureTouch family help IDT customers speed time to market through their simplified system design and easy implementation, which is achieved through the optimized touch controller architecture alleviating the need for complex firmware development.
Pricing and Availability
The new devices are currently sampling and are available at $0.70 for 10,000 units and are available in a variety of package options, including 16-pin and 20-pin TQFN and SSOP packages. Evaluation and development kits are available for testing, analysis and system emulation. Each kit consists of an evaluation tuning board, sample sensor board and a software interface for optimizing PureTouch controller configuration with a customer’s unique sensor board.
