FT6X36 Self-Capacitive Touch Panel Controller INTRODUCTION The FT6X36 Series ICs are single-chip capacitive touch panel controller IC with a built-in 16 bit enhanced Micro-controller unit (MCU).They adopt the self-capacitance technology, which supports single point and gesture touch or two points. In conjunction with a self-capacitive touch panel, The FT6X36 Series ICs implement the user-friendly input function and are widely used in various portable devices, such as smart phones, MIDs ad GPS. The FT6X36 series ICs include FT6236/FT6336/FT6436L/FT6436, the difference of their specifications will be listed individually in this datasheet. FEATURES  Self-Capacitive Sensing Techniques support single point touch and gesture or two point touch  Absolute X and Y coordinates or gesture �� [ ... ]
