3 Description

The TSC2007-Q1 device is a very low-power touch screen controller designed to work with power-sensitive, automotive touch-screen displays. It contains a complete, ultra-low power, 12-bit, analog-to-digital (A-D) resistive touch screen converter, including drivers and the control logic to measure touch pressure.

In addition to these standard features, the TSC2007‑Q1 offers preprocessing of the touch screen measurements to reduce bus loading, thus reducing the consumption of host processor resources that can then be redirected to more critical functions.

The TSC2007-Q1 supports an I2C serial bus and data transmission protocol in all three defined modes: standard, fast, and high-speed. It offers programmable resolution of 8 bits or 12 bits to accommodate different screen sizes and performance needs.

The TSC2007-Q1 is available in a 16-pin TSSOP package. The TSC2007-Q1 is characterized for the –40°C to 85°C industrial temperature range.
