DESCRIPTION

The TSC2017 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 1.6V, 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 TSC2017

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 TSC2017 supports 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 TSC2017 is available in a 12-lead,

(1.555 ±0,055mm) x (2.055 ±0,055mm), 3 x 4 array,

wafer chip-scale package (WCSP). The TSC2017 is

characterized for the –40°C to +85°C industrial

temperature range.
