TSC2007IPW, Контроллер резистивного сенсорного экрана, 4 провода, последовательный интерфейс, 12 бит

The TSC2007IPW is a Nano-power Touch Screen Controller with I?C 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 I?C 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.
