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.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
