Data Sheet Enhanced Multi-touch Capacitive Touch Screen Controller AUR3852 General Description The AUR3852 is a low-cost high-resolution single chip solution for APA capacitive touch screen. It is an 8-bit single cycle 8051 microcontroller with ICP Interface. The chip includes a 12-bit successive approximation analog-to-digital converter 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 (0.1pF to 4pF). On-chip capacitor can replace external component. This touch screen controller (TSC) with CMOS integration circuit provides an ideal choice for APA touch panel.
