The TSC2007IPW is a Nano-power Touch Screen Controller with I²C serial interface 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 1.2V, which can be supplied by a single-cell battery. It contains a complete, ultra-low power, 12-bit, analogue-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 TSC2007 offers pre-processing 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. It supports an I²C serial bus and data transmission protocol in all three defined modes, standard, fast and high-speed. It offers programmable resolution of 8 or 12 bits to accommodate different screen sizes and performance needs.
