3 Description
The TSC2007-Q1 device is a very low-power touch
screen controller designed to work with power-
sensitive, automotive touch-screen displays. 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
TSC2007‑Q1 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 TSC2007-Q1 supports an I
2
C serial bus and data
transmission protocol in all three defined modes:
standard, fast, and high-speed. It offers
programmable resolution of 8 bits or 12 bits to
accommodate different screen sizes and performance
needs.
The TSC2007-Q1 is available in a 16-pin TSSOP
package. The TSC2007-Q1 is characterized for the
–40°C to 85°C industrial temperature range.
