S7817 Touch Controller Datasheet
Introduction
The S7817 is a high performance touchscreen controller. The S7817 has 118 sensing channels (72 RX x 46 TX), for use in touchscreen displays of up to 17.3 inches diagonal.
General description
The S7817 supports self-capacitance, mutualcapacitance, hybrid sensing, and passive stylus with up to 10-finger detection. Fast report rates (up to 150 Hz) and flexible sensing frequency from 50 to 500 k Hz (configurable in 69 ns steps/cycle) are also supported.
Optimum SNR performance is achieved with onchip charge pumps and Signal Clarity TM. The controller supports 3312 nodes (72 RX x 46 TX configuration) and a maximum touchscreen size is 17.3 inches (diagonal) with a 16:10 ratio and a pitch of 5 mm.
The S7817 touch controller provides high performance hardware filtering for AC charger noise mitigation, moisture, and severe mon mode noise. The devices also offers high performance charge pump, patented CDM driving schemes, and advanced firmware algorithms. Finally, the device has patented display synchronization technology that eliminates display noise from horizontal refresh.
