Preliminary Datasheet Superior Multi-touch Capacitive Touch Screen Controller AP386X General Description The AP386X is a low-cost high-resolution single chip solution for APA (All point addressable) capacitive touch screen. It is an 8-bit single cycle 8051 microcontroller with ICP Interface. The chip includes 12-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 capacitance on the touch screen (1pF to 32pF). This touch screen controller (TSC) with CMOS integration circuit provides an ideal choice for APA touch panel.
