General Description
With accumulated PC-based chipset experiences and innovative technologies, SiS has been delivering the leading technology and better performance platforms over the past decades, and continuing offering the mature and supreme touch microprocessor. SiS9527 is developed to provide an optimal touch screen solution to OEM and ODM vendors for the new generation platform applications.
SiS9527, a superior touch panel microprocessor family integrated with a 32bit RISC processor, a 12bits Analog-to-Digital converter (ADC) with better resolution and higher sampling rate, supporting up to 60 pins of TX, and up to 96 pins of RX for up to 27” projected capacitive touch sensor, a USB or I2C interface for communicating with host system, a watchdog timer and an event timer, 128KB Flash as well as an embedded SPI port for debug purpose. In addition, SiS9527 integrated, LDO and minimizes the external passive components. To deliver the most cost-effective touch solution, it supports single layer and multi-touch TP design as well as other TP design styles. Referring to Figure1, it’s the SiS9527 system block diagram.
Moreover, SiS9527 implements various noise filter schemes to handle the wide-range coupling noise by hand/fingers operation on LCD/LED panel as well as touch algorithm. With SiS touch microprocessor architecture and its leading touch algorithm technology, SiS9527 can automatically adjust and compensate the sensing methodology to ensure the good touch quality, sensitivity and response-time under various changing humidity, temperature and other environmental factors. As well as MP tools, it can help customers reduce the design cycle time and make product time-to-market.
