INTRODUCTION
PRODUCT DESCRIPTION
The Microchip mTouch
Controller Board represents a feature-rich, fully-integrated universal touch screen
controller solution. The AR1100 Touch Screen Controller Board 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 Touch Screen Controller Board 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 Touch Screen Controller Board 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 systems to enable low-risk designs for a wide variety of touch sensing
requirements.
The AR1100 Touch Screen Controller Board supports large displays like industrial con-
trols, self-service kiosks, and POS terminals, as well as smaller tablet displays, hand-
held 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 Touch Screen Controller
Board 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.
The mTouch™ AR1100 Touch Screen Controller Board auto-detects communication
(RS-232 or USB) and uses a jumper to select between 5-wire and 4/8-wire analog
resistive touch screens. The AR1100 Touch Screen Controller Board is ready to go out
of the box with little or no configuration.
