Data Sheet

Enhanced Multi-touch Capacitive Touch Screen Controller

CS5519

General Description

Features (Continued)

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. The CS5519 is

specified over the temperature range of -40°C to

95°C.
