TI TSC2013QPWRQ1

The TSC2013-Q1 device is an ultra-low-power dual touchscreen controller designed for use with power-sensitive, low-cost touch displays in automotive infotainment and navigation systems. It features a complete ultra-low-power 12-bit analog-to-digital converter (ADC) resistive touchscreen converter, including drivers and control logic for measuring touch pressure. The TSC2013-Q1 device enables pinch-to-zoom and rotation functions through a standard four-wire interface. For all three defined modes (standard, fast, and high-speed), the device supports the I²C serial bus and data transfer protocol. The ADC within the 10- or 12-bit range can be easily programmed to customize the system and user experience.
