Resistive Type Touch Screen Controller ICs

BU21024FV-M

General Description

Packages

Unlike most resistive touch screen controllers, the

BU21024 4-wire resistive touch screen controller

enables dual-touch detection and gesture recognition.

These intelligent controllers expose a set of registers to

a HOST processor and are configured through software.

The controllers can detect single point coordinates, dual

coordinates, pinch, spread, rotate left and rotate right

gestures, enabling pan and zoom operations in

applications that previously had to rely exclusively on

capacitive touch technology. Resistive touch does not

require custom screen development which reduces

development cost, and results in faster time to market

across a family of products.

Features

Enables single touch, dual touch & gesture

recognition using standard 4-wire resistive touch

screens

Applications

Products with an LCD can benefit from pan and

zoom operations.

Adjustable touch detection threshold allows fine

tuning of pressure sensitivity for an application

Enables measurement of single point touch

pressure

Smart phones, Digital Cameras, Video Cameras,

GPS Receivers, Printers,

Copiers, automotive navigation screens, touch

kiosks

Tablet PCs , Notebook computers, LCD displays

(with USB interface)

Car navigation system, Car Audio

SPI- and I²C interface for interfacing to HOST

processor

Programmable interrupt polarity

10-bit ADC provides sufficient resolution for finger

or stylus inputs

Firmware for internal CPU may be downloaded

from HOST processor or from an EEPROM

Includes filtering options to eliminate false

coordinates

Built in support for intelligent calibration

Easy to swap X & Y coordinates or adapt to

different touch screen connections

Single 3V power supply

Available in small packages and temperature

ranges

Ideally suited for large volume automotive,

consumer, and industrial applications
