Enhanced Multi-touch Capacitive Touch Screen Controller AUR3852
General Description
The AUR3852 is a low-cost high-resolution single
chip solution for APA capacitive touch screen. It is
an 8-bit single cycle 8051 microcontroller with ICP
Interface. The chip includes a 12-bit successive
approximation analog-to-digital converter 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 AUR3852 is
specified over the temperature range of -40°C to
85°C.
The AUR3852 is available in QFN-6×6-48 and
QFN-7×7-56 packages.
