SBAS265G − OCTOBER 2002 − REVISED JANUARY 2008

Low-Voltage I/O

TOUCH SCREEN CONTROLLER

F_DEATURES

DESCRIPTION

SAME PINOUT AS ADS7846

2.2V TO 5.25V OPERATION

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 applications 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.

INTERNAL 2.5V REFERENCE

DIRECT BATTERY MEASUREMENT (0V TO 6V)

ON-CHIP TEMPERATURE MEASUREMENT

TOUCH-PRESSURE MEASUREMENT

QSPI AND SPI 3-WIRE INTERFACE

AUTO POWER-DOWN

AVAILABLE IN TSSOP-16, QFN-16, AND

VFBGA-48 PACKAGES

A_DPPLICATIONS

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

(reference 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 specified over the –40°C to

+85°C temperature range.
