SX8653

SX8653 Multitouch 15kV ESD protection 4-Wire / 5-Wire Resistive Touchscreen Controller with SPI Interface ADVANCED COMMUNICATIONS & SENSING DATASHEET -----4 GENERAL DESCRIPTION KEY PRODUCT FEATURES The SX8653 is a touch controller for 4 or 5 wire resistive touchscreen. With 4-wire touchscreen, the multitouch feature enables a completely different user interaction. It enables detection of 2 fingers on the touchscreen and several gestures like rotation and pinch/ stretch. It features a wide input supply range from 1.65V to 3.7V and low power modes to preserve current when the screen is unintentionally touched. To compute touch screen X-Y coordinates and touch pressure with precision, a low power 12-bit analog-digital converter is activated with the possibility to enable on-chip data averaging processing algorithms to reduce host activity and suppress system noise. The touch screen controller inputs have been specially designed to provide robust on-chip ESD protection of up to ±15k...
