BU21023GUL, BU21023MUV, BU21024FV-M are 4-wire resistive touch screen controller ICs produced by ROHM. They support 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.
