DESCRIPTION

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.
