Overview

The DV102011 is a comprehensive evaluation kit for the AR1000 resistive touch screen controller, featuring the mTouch technology for robust human-interface design. This kit provides a hardware platform to test 4-wire, 5-wire, and 8-wire resistive touch sensors using I2C or SPI communication. It serves as a turnkey solution for integrating touch capabilities into embedded systems with built-in drift compensation algorithms.

Why Choose This Part

The kit demonstrates the AR1000's low-power performance, drawing only 85 uA in standby and 3.0 mA typical when no touch is detected. It allows engineers to leverage 128 bytes of user EEPROM for calibration storage and features a built-in drift compensation algorithm that maintains accuracy over the component's lifetime. The support for multiple resistive technologies (4, 5, and 8-wire) provides significant design flexibility for diverse sensor sourcing.

Applications

Industrial Control Panels
Implementing rugged resistive touch interfaces that require high reliability and immunity to environmental drift.
Point-of-Sale (POS) Terminals
Integrating cost-effective touch input for transaction systems that operate over a wide temperature range.
Medical Equipment Displays
Developing touch interfaces for medical monitors that require precise input and low power consumption in standby modes.
Embedded Prototyping
Rapidly validating resistive touch sensor performance before committing to a custom PCB layout.

Getting Started

Connect the evaluation board to a PC via the included USB cable to interface with Microchip's configuration software for calibration and parameter tuning. Use the provided headers to bridge the AR1000's I2C or SPI pins to your target microcontroller for firmware development. Ensure the VDD supply is maintained between 2.5V and 5.25V as per the AR1000 electrical specifications.
