AR1020-I/ML Description

Short technical summary and product information.

The AR1020-I/ML is a touch screen controller IC designed for resistive touchscreens. It features 10-bit resolution and supports 4, 5, or 8 wire resistive touch panels. The device operates over a supply voltage range of 2.5V to 5V and draws a typical supply current of 17 mA. Communication is available via I²C, Serial, or SPI interfaces. The controller is housed in a 20-VFQFN exposed pad package (20-QFN 4x4 mm) and is surface mountable. It is specified for an operating temperature range of -40°C to 85°C, making it suitable for industrial and automotive environments. The AR1020-I/ML is RoHS3 compliant and has an MSL of 1 (unlimited).
