BU21029MUV

Datasheet 4-wire Resistive Touch Screen Controller BU21029MUV ●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. ●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[℃] 1.0[uA] (Max.) 100[uA] (Typ.) 0.8[mA] (Typ.) 12bit ●Package VQFN020V4040 4.00 mm x 4.00 mm x 1.00 mm ●Applications ■ Equipment with built-in user interface for 4-wire resistive...
