Resistive Type Touch Screen Controller ICs
BU21023GUL
BU21023MUV
BU21024FV-M(for Automotive)
General Description
Unlike most resistive touch screen controllers, the
BU21023/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
Adjustable touch detection threshold allows fine
tuning of pressure sensitivity for an application
Enables measurement of single point touch
pressure
SPI- and I
2C 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
