DESCRIPTION  
The TSC2020 is a very low power, resistive touch  
screen  
power-sensitive, handheld applications that are based  
on advanced low-voltage processors. This device  
works with a supply voltage as low as 1.6V that can  
be supplied by a single-cell battery. The TSC2020

Internal Detection of Screen Touch  
Register-Based, Programmable:

Sampling Rates, System Timing, Zoning,  
Normal/Fast Scan Mode  
contains  
a
complete, ultra-low power, 12-bit,  
analog-to-digital converter (ADC) including sensor  
drivers and the control logic to measure touch  
pressure. Unlike other resistive touch screen  
controllers, the TSC2020 is capable of detecting at  
least three touches simultaneously and delivers a  
very low power standby touch detection scheme. This  
flexibility allows for many new applications that  
require multiple touches but must remain at low  
power.  
The TSC2020 supports the I2C serial bus and data  
transmission protocol for all three defined modes:  
standard, fast, and high-speed. The TSC2020 offers  
programmable resolution, single-/multi-touch modes  
to accommodate different screen types, sizes, and  
application needs.
