Self-Capacitive Touch

Panel Controller

INTRODUCTION

The FT6236U 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 FT6236U implement the user-friendly input function and are widely used in various portable devices,

such as smart phones, MIDs ad GPS.

FEATURES

 Self-Capacitive Sensing Techniques support single point

touch and gesture or two point touch

 Absolute X and Y coordinates or gesture
