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
