The TSC2008-Q1 is a very low-power touch screen controller designed to work with power-sensitive, handheld applications that are based on advanced low-voltage processors. It works with a supply voltage as low as 1.2V, which can be supplied by a single-cell battery. 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 TSC2008-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 TSC2008-Q1 supports an SPI serial bus and data transmission. It offers programmable resolution of 8 or 12 bits to accommodate different screen sizes and performance needs.

The TSC2008-Q1 is available in a 16-pin, 4 x 4 QFN package. The TSC2008-Q1 is characterized for the –40°C to +105°C industrial temperature range.
