AP3861 Datasheet | BCD

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 (1p F to 32p F). This touch screen controller (TSC) with CMOS integration circuit provides an ideal choice for APA touch panel. The AP386X is specified over the temperature range of -40°C to 85°C. The AP386X is available in QFN-5×5-40 (for AP3860) and QFN-6×6-48 (for AP3861) packages.
