TSC2046

SBAS265C – OCTOBER 2002 – REVISED JULY 2004

Low Voltage I/O

TOUCH SCREEN CONTROLLER

FEATURES

DESCRIPTION

z SAME PINOUT AS ADS7846

The TSC2046 is a next-generation version to the ADS7846

4-wire touch screen controller which supports a low-voltage

I/O interface from 1.5V to 5.25V. The TSC2046 is 100% pin-

compatible with the existing ADS7846, and will drop into the

same socket. This allows for easy upgrade of current appli-

cations to the new version. The TSC2046 also has an on-

chip 2.5V reference that can be used for the auxiliary input,

battery monitor, and temperature measurement modes. The

reference can also be powered down when not used to

conserve power. The internal reference operates down to

2.7V supply voltage, while monitoring the battery voltage

from 0V to 6V.

z 2.2V TO 5.25V OPERATION

z 1.5V TO 5.25V DIGITAL I/O

z INTERNAL 2.5V REFERENCE

z DIRECT BATTERY MEASUREMENT (0V to 6V)

z ON-CHIP TEMPERATURE MEASUREMENT

z TOUCH-PRESSURE MEASUREMENT

z QSPI^TMAND SPI^TM3-WIRE INTERFACE

z AUTO POWER-DOWN

z AVAILABLE IN TSSOP-16, QFN-16, AND

The low-power consumption of < 0.75mW typ at 2.7V (refer-

ence off), high-speed (up to 125kHz sample rate), and on-

chip drivers make the TSC2046 an ideal choice for battery-

operated systems such as personal digital assistants (PDAs)

with resistive touch screens, pagers, cellular phones, and

other portable equipment. The TSC2046 is available in

TSSOP-16, QFN-16, and VFBGA-48 packages and is speci-

fied over the –40°C to +85°C temperature range.
