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 I2C 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.
