TSC2014 Touch Screen Controller with I²C
Texas Instruments TSC2014 Touch Screen Controller with I2C is a very low-power device designed to work with power-sensitive, handheld applications that are based on advanced low-voltage processors. The TI TSC2014 works with a supply voltage as low as 1.2V, which can be supplied by a single-cell battery. This TI touch screen controller 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 TSC2014 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. The TSC2014 supports an I2C serial bus and data transmission protocol in all three defined modes: standard, fast, and high-speed.
