BU21029MUV - 4-wire Resistive Touch Screen Controller

ROHM

General 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.

Key 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.
