The TSC2008 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 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 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 is available in a 12-lead,(1,555 ±0,055mm) x (2,055 ±0,055mm) 3 x 4 array, wafer chip-scale package (WCSP), and a 16-pin, 4 x 4 QFN package. The TSC2008 is characterized for the -40°C to +85°C industrial temperature range.
