DESCRIPTION
The TSC2007-Q1 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-Q1 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-Q1 supports an I
2
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.
The TSC2007-Q1 is available in a 16-pin TSSOP package. The TSC2007-Q1 is characterized for the –40°C to
+85°C industrial temperature range.
