●Description

Unlike most resistive touch screen controllers, the BU21023/ BU21024 4-wire resistive touch screen controllers enable

dual-touch detection and gesture recognition. These intelligent controllers expose a set of registers to a host processor and

are software configurable. 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 panel development which reduces development cost

and results in faster time to market across a family of products.

●Features

1) Enables single touch, dual touch & gesture recognition using standard 4-wire resistive touch panels

2) Adjustable touch detection threshold allows fine tuning of pressure sensitivity for an application

3) Enables measurement of single point touch pressure

4) SPI and I²C like interface for interfacing to host processor

5) Programmable interrupt polarity

6) 10-bit ADC provides sufficient resolution for finger or stylus inputs

7) Firmware for internal CPU may be downloaded from Host processor or from an EEPROM

8) Includes filtering options to eliminate false coordinates

9) Built in support for intelligent calibration

10) Easy to swap X & Y coordinates or adapt to different touch panel connections

11) Single 3V power supply

12) Available in a range of small package sizes and temperature ranges

13) Ideally suited for large volume automotive, consumer and industrial applications

●Application

・Products with a LCD that can benefit from pan and zoom operations.

・Smart phones, Digital Cameras, Video Cameras, GPS Receivers, Printers,

Copiers, automotive navigation panels, touch kiosks

・Tablet PCs , Notebook computers, LCD displays (with USB interface)

●Line up matrix
