4-wire resistive

Touch Screen Controller

BU21021GUL

●General Description

●Key Specification

■ Power supply voltage

■ Temperature range

■ Standby current

BU21021GUL is a resistive touch screen controller,

which is capable of detecting 2 points touch with a

legacy 4-wire resistive touch screen. BU21021GUL is

capable of detecting X/Y coordinates, touch pressure in

1 point detection mode, and a pair of X/Y coordinates in

2 point detection mode.

It is also capable of recognizing multiple finger gestures

from coordinate data variation and notifying to host with

gesture detection flags respectively.

2.7V to 3.6V

-25℃ to 85℃

60uA (Typ.)

4.0mA (Typ.)

12bit

■ Sleep current

■ Operating current

■ Coordinate resolution

●Package

BU21021GUL employs embedded CPU for noise

filtering, coordinate calculation, gesture detection and

other signal processing required on a chip.
