1 INTRODUCTION
The ST1624 is a mutual 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.
