Resistive Touch Sensing Solutions Slide 12

In summary, STMicroelectronics offers within the S-Touch portfolio resistive touch sensing technology as it applies to LCD screens. There are several advantages to using these solutions such as low CPU load, low bus use, tolerance for slow ISR response, immunity to system level noise, and a simple device driver. There are currently has two resistive touch screen controller devices available: the STMPE811 which has eight GPIO channels and the STMPE610 which has six GPIO channels.
