DESCRIPTION  
10-Bit or 12-Bit Resolution  
Sampling Rates  
The TSC2006 is a very low-power touch screen  
controller designed to work with power-sensitive,  
handheld applications that are based on advanced  
low-voltage processors. It works with a supply voltage  
as low as 1.2V, which can be supplied by a  
System Timing  
On-Chip Temperature Measurement  
Touch Pressure Measurement  
Auto Power-Down Control  
Low Power:  
single-cell battery. It contains  
a
complete,  
ultralow-power, 12-bit, analog-to-digital (A/D) resistive  
touch screen converter, including drivers and the  
control logic to measure touch pressure.  
707µW at 1.8V, 50SSPS  
In addition to these standard features, the TSC2006  
offers  
measurements to reduce bus loading, thus reducing  
the consumption of host processor resources that can  
then be redirected to more critical functions.  
544µW at 1.6V, 50SSPS

69µW at 1.6V, 8.2kSPS Eq. Rate  
43µW 1.2V, 8.2kSPS Eq. Rate  
The TSC2006 supports an SPI-compatible serial bus  
up to 25MHz. It offers programmable resolution of 10  
or 12 bits to accommodate different screen sizes and  
performance needs.  
Enhanced ESD Protection:  
±8kV HBM  
±1kV CDM  
Target ±25kV Air Gap Discharge  
The TSC2006 is available in a miniature 20-lead,  
4 × 4 QFN package, and is characterized for the  
–40°C to +85°C industrial temperature range.  
Target ±12kV Contact Discharge
