Data Sheet Enhanced Multi-touch Capacitive Touch Screen Controller CS5519 General Description The CS5519 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 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.
