The Touch Sensor 32-TQFP (part number 71T5349) is a digital charge-transfer QMatrix IC designed for touch sensing applications. It supports up to 16 or 24 keys, allowing for flexible key size and shape configurations within a single panel. The device operates with a supply voltage range of +3V to +5.5V and features a SPI interface for communication. It is capable of projecting touch through various dielectric materials, including glass and plastic, up to 50mm thick. The sensor includes features such as individual key sensitivity adjustment, 100% autocalibration, and noise suppression, making it suitable for environments subject to humidity, dirt, and vandalism. The operating temperature range is from -40¬8C to +105¬8C, and it is compliant with RoHS standards. The low external component count and robust design make it a cost-effective solution for applications in security panels, industrial keyboards, and consumer appliances.
