Product Summary
The TSC2017IYZGR is a 12-bit, nanopower, 4-wire micro touch screen controller with i2c interface. It is designed to work with power-sensitive, handheld applications that are based on an advanced low-voltage processor. The TSC2017IYZGR works with a supply voltage as low as 1.6V, which can be supplied by a single-cell battery. It contains a complete, ultra-low power, 12-bit, analog-to-digital (A/D) resistive touch screen converter, including drivers and the control logic to measure touch pressure. The applications of the TSC2017IYZGR include: Cellular Phones, PDA, GPS, and Media Players, Portable Instruments, Point-of-Sale Terminals, Multiscreen Touch Control Systems.
