DESCRIPTION
The TSC2007 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 1.2V, 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 TSC2007
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 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 or 12 bits to
accommodate different screen sizes and
performance needs.
The TSC2007 is available in a 12-lead,
(1.555 ±0.055mm) x (2.055 ±0.055mm), 3 x 4 array,
wafer chip-scale package (WCSP), and a 16-pin,
TSSOP package. The TSC2007 is characterized for
the –40°C to +85°C industrial temperature range.
