آی سی XPT2046 یک کنترل کننده صفحات LCD تاچ می باشد.
General Description :
The XPT2046 is a 4-wire resistive touch screen controller that incorporates a 12-bit 125 kHz sampling SAR type A/D converter.
The XPT2046 operates down to 2.2V supply voltage and supports digital I/O interface voltage from 1.5V to VCC in order to connect low voltage uP.
The XPT2046 can detect the pressed screen location by performing two A/D conversions. In addition to location, the XPT2046 also measures touch screen pressure.On-chip VREF can be utilized for analog auxiliary input, temperature measurement and battery monitoring withthe ability to measure voltage from 0V to 5V.
The XPT2046 also has an on-chip temperature sensor.
Features :
12 bit SAR type A/D converter with S/H circuit
Low voltage operation (VCC = 2.2V ∼ 3.6V)
Low voltage digital I/F (1.5V ∼ VCC)
4-wire I/F
Sampling frequency: 125 kHz (max)
On-Chip voltage reference (2.5V)
Pen pressure measurement
On-chip thermo sensor
Direct battery masurement
Low power consumption (260μA)
Package 16pin QFN
