The ST1633 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.
The ST1633 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 ST1633 makes it suitable for modern touch screen application
which contain a vivid and high density display, like smart phone, portable navigation device and
touch-enabled media player, etc..
