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  
On-Chip, Programmable PENIRQ Pull-Up  
Comprehensive Reset Schemes:  
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:
