Overview
Data Sheet Enhanced Multi-touch Capacitive Touch Screen Controller AP389X General Description Features (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 capacitance on the touch screen (0.
1pF to 4pF).
On-chip capacitor can replace external component.
