TSC2007-Q1 - Automotive Nano-Power Touch Screen Controller with I2C Serial Interface

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.
