The TSC2004 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, 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 TSC2004 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 TSC2004 supports an I2C serial bus and data transmission protocol in all three defined modes: standard, fast, and high-speed. It offers programmable resolution of 10 or 12 bits to accommodate different screen sizes and performance needs.
The TSC2004 is available in a miniature, 18-lead, 5 x 5 array, (2.554 ±0.54)mm x (2.554 ±0.54)mm wafer chip-scale package (WCSP), and a 20-pin, 4 x 4 QFN package. Both packages are characterized for the -40°C to +85°C industrial temperature range.
