3. Functional Description
3.1. General Introduction
This section provides an overview of the SX8652 architecture, device pinout and a typical application.
The SX8652 is designed for 4-wire and 5-wire resistive touch screen applications. The touch screen or touch panel is the
resistive sensor and can be activated by either a finger or stylus. When the top layer is pressed, it makes contact with the
bottom sheet and the touch location can be measured.
As shown in Figure 5 with a 4-wire panel, the touch screen coordinates and touch pressure are converted into SPI format
by the SX8652 for transfer to the host. The auxiliary input can be used to convert with 12-bit resolution any analog input in
the supply range. It can also serves as an external synchronisation input to trig the touchscreen acquisition as described in
the Application Information section.

A 5-wire touchscreen application is shown in Figure 6. The 5-wire top sheet acts as a voltage measuring probe. The
measurement accuracy is not affected by damage on this sheet and consequently the reliability is improved but the touch
pressure can not be calculated.
