SBAS257 – FEBRUARY 2002

PDA ANALOG INTERFACE CIRCUIT

FEATURES

APPLICATIONS

● PERSONAL DIGITAL ASSISTANTS

● 4-WIRE TOUCH SCREEN INTERFACE

● RATIOMETRIC CONVERSION

● SINGLE 2.7V TO 3.6V SUPPLY

● SERIAL INTERFACE

● CELLULAR PHONES

● MP3 PLAYERS

DESCRIPTION

● INTERNAL DETECTION OF SCREEN TOUCH

The TSC2000 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, and an 8-bit Digital-to-Analog (D/A)

converter output for LCD contrast control. The TSC2000

interfaces to the host controller through a standard SPI™

serial interface. The TSC2000 offers programmable resolution

and sampling rates from 8- to 12-bits and up to 125kHz to

accommodate different screen sizes.

● PROGRAMMABLE 8-, 10-, OR 12-BIT

RESOLUTION

● PROGRAMMABLE SAMPLING RATES

● DIRECT BATTERY MEASUREMENT (0.5V to 6V)

● ON-CHIP TEMPERATURE MEASUREMENT

● TOUCH-PRESSURE MEASUREMENT

● FULL POWER-DOWN CONTROL

● TSSOP-20 PACKAGE

The TSC2000 also offers two battery-measurement inputs,

one of which is 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 TSC2000 is

available in a TSSOP-20 package.

SPI is a registered trademark of Motorola.

US Patent No. 624639.
