(Continued) The AP389X is a low-cost high-resolution single chip solution for APA capacitive touch screen. It is an 8-bit single cycle 8051 microcontroller with I2C Interface. The chip includes 8-bit successive approximation analog-to-digital converters with an I2C interface and multiplexer-switcher circuits for flexible measurement of analog signal from APA panel. An accurate switched-capacitor integrator is built-in and it can auto calibrate the pixel parameters for a wide range of capacitanc.
