1 INTRODUCTION
The ST1633i is a capacitive sensing controller for small size projected capacitive touch screen. It is a RISC microcontroller with capacitor charge, capacitor sensing, slave I2C interface, general purpose I/O and embedded non-volatile memory. Internal program and cooperating digital circuit convert finger / capacitor stylus physical touching into button pressing message or multiple coordination information for application. The maximum fingers identification ability is up to five. The ST1633i uses low profile QFN package and support ITO electrode on glass or film substrate. Hence, slim and small touch panel module is realizable. And more, low electromagnetic interference of ST1633i makes it suitable for modern touch screen application such as industrial equipment and automotive vehicle. Ver 1.
