SiS Announces Multi-Touch Panel Control Processor

Silicon Integrated Systems (SiS) today unveiled its latest product in multi-touch screen technology, a projected capacitive multi-touch panel control processor ?SiS810.

To further catch ride with the popularity of touch-screen iPhone as well as oncoming launch of Window 7, SiS810 was developed to provide a multi-touch screen solution to OEM and ODM vendors for the new generation platform.

SiS810, a 32bit RISC touch-screen panel processor with a 12bits Analog-to-Digital Converter (12bits ADC) supports 42 sensor inputs for the panel size up to 8.9 inches, enabling either SPI or I2C bus to cope with diverse communication interfaces to host platform. An embedded UART port is designed for further debugging and specific R&D applications. Implemented Watchdog Timer and Event Timer serve add-on-value functions for flexibility and creativity. Besides, Power on Demand technology design effectively reduces power-consumption to meet environmental protection requirements. More than that, GPIO feature ensures expandability on both H/W and S/W applications. Taking advantage of above features, SiS810 enables designers to create new usage models for the small and medium panel size (5 to 8.9 inches LED/LCD panel size) multi-touch products such as small form factor Notebook, mobile internet device (MID), Netbook, Tablet PC, Car PC devices, GPS PND devices, Stock Information devices and etc.



The embedded 12-bit ADC feature allows users to experience an operating environment of 300ppi high resolution at 100Hz sampling rate. This design is just right for those user-oriented vendors to deliver real-time playback. The high speed MCU with a filtering management algorithm implements to manage vivid gestures for enabling more direct and natural interaction in your applications. To effective filter out the unexpected coupling noise by hand/fingers operation on LCD/LED panel, SiS810 has implemented a unique know-how based on the perfect architecture of its H/W, firmware and embedded filters. With its technology algorithm, it can automatically adjusting and compensating the sensing methodology to ensure the good touch quality, sensitivity and response-time under the humidity and temperature environmental changes factors.

The preeminent multi-touch panel control processor, SiS810 is compliant with the Microsoft Windows 7 logo criteria. SiS said that it would continue to strengthen its product portfolio for broader market segments and also offer the full software package solutions to support Windows XP, Windows Vista, WinCE and Linux applications in various touch screen sizes applications.

SiS810 adopts the Halogen free 9mmx9mm technology and 64-pin QFN package. Engineer sample is available now for designing and validating and mass production is expected to start in early Q3, 2009.
