Texas Instruments  TSC2006IRTJT

The TSC2006 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, ultralow-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 TSC2006 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 TSC2006 supports an SPI-compatible serial bus up to 25MHz. It offers programmable resolution of 10 or 12 bits to accommodate different screen sizes and performance needs.

The TSC2006 is available in a miniature 20-lead, 4 × 4 QFN package, and is characterized for the -40°C to +85°C industrial temperature range.
