AR1000 SERIES RESISTIVE TOUCH SCREEN CONTROLLER
1.0
DEVICE OVERVIEW
The Microchip mTouchTM AR1000 Series Resistive
Touch Screen Controller is a complete, easy to
integrate, cost-effective and universal touch screen
controller chip.
The AR1000 Series has sophisticated proprietary
touch screen decoding algorithms to process all touch
data, saving the host from the processing overhead.
Providing filtering capabilities beyond that of other
low-cost devices, the AR1000 delivers reliable, vali-
dated, and calibrated touch coordinates.
Using the on-board EEPROM, the AR1000 can store
and independently apply the calibration to the touch
coordinates before sending them to the host. This
unique combination of features makes the AR1000 the
most resource-efficient touch screen controller for
system
designs,
including
embedded
system
integrations.
1.1
Applications
The AR1000 Series is designed for high volume, small
form factor touch solutions with quick time to market
requirements – 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
