Features
■ True multi-touch – Independent XY tracking with 10 simultaneous touches in real time – Supports 21TX and 40RX channels and 1 FLOAT pin
■ Single chip solution – Supports 5.5 inch to 7 inch screen size with 4mm sensor pitch – Supports thin flexible touch-display highly capacitive panel types – Supports LTPO display panels with dynamic refresh rates
■ Advanced Analog Front End (AFE) – Simultaneous mutual sensing and self-sensing support on all the channels – Support for thin flexible touch display modules through proprietary node compensation hardware – Differential architecture with ability to configure in single-ended mode – Multiple scanning methods with multi-TX drive for high SNR and provide high noise immunity – High drive capability charge-pump to drive high capacitive panels
■ High SNR – Very low intrinsic noise to improve the device SNR and provide very high sensitivity – Extremely strong common mode charger noise rejection – Advanced filtering techniques for high noise immunity
■ SYNC support – Supports SYNC Mode and Non-SYNC Mode of operation – Supports single SYNC pin that can be used as VSYNC, HSYNC or Embedded VSYNC – Useful for quad high definition display synchronization during both mutual- sensing and self-sensing – Seamless support of variable display rate from 1Hz to 120Hz
