AR1100 RESISTIVE USB AND RS-232 TOUCH SCREEN CONTROLLER
1.0
OVERVIEW
The Microchip mTouchTM AR1100 Analog Resistive
USB and RS-232 Touch Screen Controller represents
a feature-rich, fully-integrated universal touch screen
controller solution. The AR1100 automatically selects
between USB and RS-232 communication protocols,
as well as supports 4, 5 or 8-wire analog resistive touch
screens from any of a variety of touch screen
manufacturers. The AR1100 dynamically adapts to the
various touch screen electrical characteristics such as
sensitivity, contact resistance, and capacitance to
provide optimal performance with minimal design time.
Building on the AR1000 series, the new AR1100 offers
customers an easy-to-integrate solution for low-cost,
high-performing resistive touch with the advantages of
USB plug and play, support for USB mouse or digitizer,
advanced touch response and accuracy, field flash
updatability, and free drivers for most operating sys-
tems to enable low risk designs for a wide variety of
touch sensing requirements.
The AR1100 supports large displays like industrial con-
trols, self-service kiosks, and POS terminals, as well as
smaller tablet displays, handheld consumer devices,
and medical devices.
Resistive touch provides the advantages of easy
integration, low total system cost and acceptance of
finger, glove or stylus input, and USB communication is
the industry standard for attaching peripherals to a
computer. The AR1100 is an easy-to-integrate touch
screen controller that meets all of these needs in a
single-chip solution or production ready-board product.
The device comes with free drivers for most major
operating systems, making it easy for designers to
quickly create low-risk touch interface solutions.
1.1
Applications
The AR1100 is suitable for any application that requires
fast, accurate and reliable integration of touch –
including, but not limited to:
Mobile communication devices
Personal Digital Assistants (PDA)
Global Positioning Systems (GPS)
Touch Screen Monitors
KIOSK
Media Players
Portable Instruments
Point of Sale Terminals
