The TSC2007 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 1.2V, 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 TSC2007 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 TSC2007 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.
The TSC2007 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, TSSOP package. The TSC2007 is characterized for the -40°C to +85°C industrial temperature range.
