TSC367

The TSC367 is designed as one kind of highly integrated PDA analog interface circuit. This device can be used in wide range of applications such as (1)personal digital assistants; (2)cellular phones; (3)MP3 players; (4)internet appliances; (5)smartphones. It contains a complete 12-bit A/D resistive touch screen converter (ADC) including drivers, touch pressure measurement capability, keypad controller, and 8-bit D/A converter (DAC) output for LCD contrast control.

Features of the TSC367 are:(1)SPI Serial Interface;(2)4-Wire Touch Screen Interface;(3)Internal Detection of Screen Touch and Keypad Press;(4)Touch Pressure Measurement;(5)Ratiometric Conversion;(6)Programmable 8-, 10- or 12-Bit Resolution;(7)Programmable Sampling Rates Up to 125 kHz;(8)Direct Battery Measurement (0 to 6 V);(9)Full Power-Down Control;(10)8-Bit Current Output DAC;(11)6 GPIO Pins;(12)Single 2.7-V to 3.6-V Supply;(13)On-Chip Crystal Oscillator.

The absolute maximum ratings of the TSC367 can be summarized as:(1)Supply voltage: 4 V;(2)Ground voltage differences: ±0.1 V;(3)Digital input voltage: -0.3 V to (DVDD + 0.3 V);(4)Analog input voltage: -0.3 V to (AVDD + 0.3 V);(5)Ambient temperature under bias, TA: -40°C to 125°C;(6)Storage temperature, Tstg: -55°C to 150°C;(7)Junction temperature, TJ: 150°C;(8)Lead temperature 1,6 mm (1/16 inch) from case for 10 seconds: 260°C.
