15kV ESD Low Power 4-Wire / 5-Wire Resistive

Touchscreen Controller with SPI Interface

ADVANCED COMMUNICATIONS & SENSING

DATASHEET

4

The SX8652 is a very low power, high reliability controller

for 4-wire and 5-wire resistive touch screens used in PDAs,

portable

instruments

and

point-of-sales

terminal

applications. 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

±15kV in both HBM and Contact Discharge, and eliminates

the need for external protection devices. The SX8652 is

controlled by a high speed SPI™ serial interface.

The SX8652 is available in a 4.0 mm x 3.0 mm 14-DFN

package and a 1.5 mm x 2.0 mm wafer level chip scale

package (WLCSP) for space conscience applications.
