The TSC2005 is a very low-power touch screen controller designed to work with power-sensitive, handheld applications that are based on an advanced low-voltage processor. It works with a supply voltage as low as 1.6V, 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 TSC2005 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 TSC2005 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 TSC2005 is available in a miniature 18-lead,
5 x 6 array, 2.608 x 3.108 mm wafer chip-scale package (WCSP). The device is characterized for the -40°C to +85°C industrial temperature range.
