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.
