AR1021T-I/SO

AR1021T-I/SO General Description

Microchip's AR1021T-I/SO product, part of the mTouch™ AR1000 Series, is a cost-effective and universally compatible resistive touch screen controller chip. Featuring proprietary touch screen decoding algorithms, the AR1000 Series delivers accurate touch coordinates and relieves the host system of unnecessary overhead. With onboard EEPROM for storing calibration data, the AR1021T-I/SO ensures consistent and reliable touch input for embedded designs. Supporting both I2C™ Compatible and SPI communication protocols, this touch screen controller offers flexibility and ease of integration. For UART communication, consider the AR1011 touch screen controller as an alternative solution

Features
