SIS reveals SiS9730 EM touch processor

Silicon Integrated Systems reveals its first generation low-power EM touch processor – the SiS9730 designed for small form-factor E-Book reader, Tablet PC and Drawing Tablet and is expected to be demonstrated at Taipei Computex in June.

As SiS said the advantages of the EM touch subsystem over the capacitive touch subsystem is that EM touch subsystem does not impact the light transmission rate, via embedding the antenna sensing board beneath the display panel, and thus is extremely suitable for serving as the human interface device for both the reflective electronic display device, and the active TFT LCD.


“SiS9730 adopts an innovative tracking algorithm with low-power technology design, providing high precision pressure detection capability up to 1024-level, high precision resolution with the accuracy of 2540 ppi, high 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. SiS9730 integrates the MCU, flash ROM, LDO and Analog Front End to ultimately reduce the components cost, and thus board estate, supporting various host interface such as UART/I2C/SPI buses to widely adapt to various host systems of e-Book reader, or TFT Tablet PC. With 14×14 mm TQFP package technology, the EM touch daughter card can easily fit into a smaller and thin module for either e-paper panel or TFT LCD panel. “

“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.”
