3 Description
The TSC2013-Q1 device is a very low-power dual-
touch screen controller designed to work with power-
sensitive, low-cost touch-screen displays in
automotive infotainment and navigation systems. It
contains a complete, ultralow-power, 12-bit, analog-
to-digital (ADC) resistive touch-screen converter,
including drivers and the control logic to measure
touch pressure.
The TSC2013-Q1 device enables pinch, rotate, and
zoom functionality over a standard four-wire interface.
The device supports an I²C serial bus and data
transmission protocol in all three defined modes:
standard, fast, and high-speed. The 10 or 12-bit ADC
within is easily programmable to customize system
and user experience.
