Touch Screen Controller ICs
Resistive Type Touch Screen Controller ICs
BU21023GUL, BU21023MUV, BU21024FV-M
No.11105EAT01
ā—¸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.
