TSC2100IRHB

Product Summary

The TSC2100IRHB is a highly integrated touch screen controller with on-chip processor and audio codec. The touch screen portion of the TSC2100IRHB contains a 12-bit 4-wire resistive touch screen ADC complete with drivers, and interfaces to the host controller through a standard SPI serial interface. The on-chip processor provides extensive features specifically designed to reduce host processor and bus overhead, with capabilities that include fully automated operating modes, programmable conversion resolution up to 12 bits, programmable sampling rates up to 125 kHz. The applications of the TSC2100IRHB include Personal Digital Assistants, Smart Cellular Phones, MP3 Players.
