TOUCH SCREEN CONTROLLERS
NTS1100
32 Channel Touch Key Input Processor with MCU
DESCRIPTION
NTS1100 series are an integrated touch sensor chip with on-chip environmental calibration. These detect 8,16,24,30,32 capacitive sensor inputs and transmits the results to host controller using interrupts. NTS1100 series implement button, scroll bar and wheel type touch sensors. Also, NTS1100 series reduce development time, and accelerate product introduction, therefore these lower overall system costs. For low-power system, these have sleep mode. If NTS1100 series are in power sleep mode, input interrupt signals by external switches or communications will be used for wake-up sources. NTS1100 series are suitable for multimedia devices and electric home appliances - MP3, PMP, TV, refrigerator, audio system, microwave, doorlock, mobile phone, VCR, Home Theater and electronic cooker, etc.

NTS 2000
32 ch Touch Screen Processor with MCU
DESCRIPTION
NTS2000 series are an integrated touch sensor chip with on-chip environmental calibration. These detect 16,24,32 capacitive TSP(Touch Screen Panel) channel and transmit the results to host controller using interrupts. Also, NTS2000 series reduce development time, and accelerate product introduction, therefore these lower overall system costs. For low-power system, these have sleep mode. If NTS2000 series are in power sleep mode, input interrupt signals by external switches will be used for wake-up sources. NTS2000 series are suitable for multimedia devices and electric home appliances - PMP, Laptop, NetBook, mobile phone and remote control, etc.
FEATURES
