CS5519
CS5519 is Enhanced Multi-touch Capacitive Touch Screen Controller manufactured by BCD.
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 (0.1p F to 4p F). On-chip capacitor can replace external ponent. 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.
The CS5519 is available in QFN-7×7-56 and QFN-8×8-68 packages.
