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. 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.

This pin also can be configured as RXD of UART 1
Ground Voltage. 0V
Internal Regulator Output. 1.6V to 2.0V
Typical decoupling capacitors of 0.1F and 10F should
be connected between VDD18 and VSS
Supply Voltage. 2.8V to 3.6V
A good decoupling capacitor between VDD33 and VSS is
critical for good performance
