BU21029MUV - 4-wire Resistive Touch Screen Controller

Description

Unlike most resistive touch screen controllers, the BU21029MUV 4-wire resistive touch-screen controller can generate data that enables dual touch detection.

The Host processor can use this data to detect single and dual point coordinates.

Features

  • Single and dual touch detection for standard 4-wire resistive touch screens.
  • I2C-like interface for interfacing with the host processor.
  • 12-bit resolution.
  • Single 1.65V to 3.60V supply.
  • Power on reset.
  • Auto power down control.
  • Built-in clock oscillator circuit.
  • Key Specifications.
  • Power supply voltage.
  • Temperature range.
  • Standby current.
  • Sleep current.
  • Operating current.
  • Coordinate resolution 1.65[V]～3.60[V] -20[℃]～85[℃] 1.
