Low-power EM touch processor from SiS

SiS unveiled its first generation low-power EM touch processor, the SiS9730. It aims to create new usage model for pen writing applications for small form-factor E-Book reader, Tablet PC and Drawing Table. It is expected to be demonstrated at Taipei Computex in June. One advantage that the EM touch subsystem has over the capacitive touch subsystem is that the EM touch subsystem does not impact the light transmission rate, via embedding the antenna sensing board beneath the display panel. It is thus suggested for serving as the human interface device for both the reflective electronic display device, and the active TFT LCD.

SiS9730 adopts a tracking algorithm with low-power technology design. It has a pressure detection capability up to 1024-level, high precision resolution with the accuracy of 2540 ppi, data transfer rate up to 200 pps, for up to 12" panel size. It also supports the wake-up function of powering on the deploying system when the pen is proximate to the panel. It also integrates the MCU, flash ROM, LDO and Analog Front End. It also supports various host interfaces such as UART/I2C/SPI buses to adapt to various host systems of e-Book reader, or TFT Tablet PC.

"As an IC design vendor, SiS dedicates to developing innovative technologies for offering consumer electronics IC to enhance user experience and efficiency for the 3C consumer market." said Michael Chen, President at SiS. "SiS will continue developing the wide range of touch technologies solutions to meet the needs of the diversified products applications and markets, while providing users with more humanization user interface."

Package: 14x14 mm TQFP.
