TSC2046E

SBAS417B − JUNE 2007 − REVISED JANUARY 2008

Low Voltage I/O

TOUCH SCREEN CONTROLLER

F_DEATURES

DESCRIPTION

Same Pinout as ADS7846

2.2V to 5.25V Operation

The TSC2046E is the next-generation version of the

ADS7846 4-wire touch screen controller, supporting a

low-voltage I/O interface from 1.5V to 5.25V. The

TSC2046E is 100% pin-compatible with the existing

ADS7846, and drops into the same socket. This design

allows for an easy upgrade of current applications to the

new version. The TSC2046E 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

a supply voltage of 2.7V, while monitoring the battery

voltage from 0V to 6V.

1.5V to 5.25V Digital I/O

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

Exceeds IEC 61000-4-2 ESD Requirements

− + 15kV Contact Discharge

− No External Components Needed

Available In TSSOP-16, QFN-16, and

VFBGA-48 Packages

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 TSC2046E 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

TSC2046E is available in TSSOP-16, QFN-16, and

VFBGA-48 packages and is specified over the –40°C to

+85°C temperature range.
