DESCRIPTION

· The BU21024FV-M is a silicon monolithic integrated circuit designed for resistive touch screen control.
· It supports dual-touch detection and gesture recognition, enabling pan and zoom operations.
· The controller is configurable through software and interfaces with a HOST processor via SPI or I2C.
· It is suitable for applications requiring single or dual touch coordinates and gesture recognition without custom screen development.

FEATURES

· Supports single and dual touch & gesture recognition on standard 4-wire resistive touch screens.
· Features adjustable touch detection threshold for pressure sensitivity tuning.
· Equipped with a 10-bit ADC for high-resolution input detection.
· Offers SPI and I2C interfaces for HOST processor communication.
· Includes built-in filtering options and intelligent calibration support.
· Operates on a single 3V power supply and is available in compact packages.

APPLICATIONS

· Ideal for devices with LCDs requiring pan and zoom functionalities.
· Suitable for smartphones, digital cameras, GPS receivers, and automotive navigation systems.
· Applicable in tablet PCs, notebook computers, and LCD displays with USB interfaces.
· Used in car navigation systems and car audio units.
