SX8655

SX8654/SX8655/SX8656 Haptics Enabled 4/5-Wire Resistive Touchscreen Controller with Proximity Sensing ADVANCED COMMUNICATIONS & SENSING GENERAL DESCRIPTION The SX8654, SX8655 and SX8656 belong to a family of high performance haptics enabled 4/5-wire resistive touch screen controller with proximity detection, optimized for hand held applications such as mobile phones, portable music players, game machines, point-of-sales terminal and other consumer and industrial applications. They feature a wide input supply range from 2.3V to 3.6V. The controller computes touch screen X-Y coordinates and touch pressure with a precision, low power 12-bit analog-digital converter. On-chip data averaging processing algorithms can be activated to reduce host activity and suppress system noise. The processing core features low power modes which intelligently minimize current in operation as well as in automatic shut-down. A capacitive proximity detection circuit has been integrated into the SX8654 and SX8...
