DESCRIPTION

ꢀ INTERNAL DETECTION OF SCREEN TOUCH

The TSC2200 is a complete PDA analog interface circuit. It

contains a complete 12-bit, Analog-to-Digital (A/D) resistive

touch screen converter including drivers, the control to mea-

sure touch pressure, keyboard controller, and an 8-bit Digital-

to-Analog (D/A) converter output for LCD contrast control.

The TSC2200 interfaces to the host controller through a

standard SPI™ serial interface. The TSC2200 offers program-

mable resolution and sampling rates from 8- to 12-bits and up

to 125kHz to accommodate different screen sizes.

RESOLUTION

ꢀ PROGRAMMABLE SAMPLING RATES

ꢀ DIRECT BATTERY MEASUREMENT (0.5V to 6V)

ꢀ ON-CHIP TEMPERATURE MEASUREMENT

ꢀ TOUCH-PRESSURE MEASUREMENT

ꢀ FULL POWER-DOWN CONTROL

The TSC2200 also offers two battery-measurement inputs

capable of reading battery voltages up to 6V, while operating

at only 2.7V. It also has an on-chip temperature sensor

capable of reading 0.3°C resolution. The TSC2200 is available

in a TSSOP-28 and a QFN-32 package.
