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.
