(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated is not implied. Exposure to absolute-maximum rated conditions for extended periods may affect device reliability.
(2) Test method based on IEC standard 61000-4-2. Contact Texas Instruments for test details.

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, 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 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 to +85 industrial temperature range.
