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.

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.
