1FEATURES
234• 4-Wire Touch Screen Interface• Single 1.6Vto 3.6V Supply/Reference Portable Instruments• Ratiometric Conversion Point-of-Sale Terminals• Effective Throughput Rate: Multiscreen Touch Control– Upto 20kHz (8-Bit)or 10kHz (12-Bit) Preprocessingto Reduce Bus Activity DESCRIPTIONI2C Interface Supports: The TSC2017isa very low-power touch screen
– Standard, Fast, and High-Speed Modes controller designed to work with power-sensitive,
Simple, Command-Based User Interface: handheld applications that are basedon an advanced
low-voltage processor.It works witha supply voltage
– TSC2003/TSC2007 Compatible as low as 1.6V, which can be supplied bya
– 8-or 12-Bit Resolution single-cell battery.It containsa complete, ultra-low
On-Chip Temperature Measurement power, 12-bit, analog-to-digital (A/D) resistive touch
screen converter, including drivers and the control
• Touch Pressure Measurement logicto measure touch pressure.
• Digital Buffered PENIRQ additionto these standard features, the TSC2017
• On-Chip, Programmable PENIRQ Pull-Up offers preprocessing of the touch screen
• Comprehensive Reset Schemes: measurementsto reduce bus loading, thus reducing
Power-On, Software, and Hardware Resets the consumptionof host processor resources that can
thenbe redirectedto more critical functions.
• Auto Power-Down Control Low Power (12-Bit): The TSC2017 supportsI2C serial bus and data
transmission protocol in all three defined modes:
– 39.31μAat 1.8V, Fast Mode, 8.2kHz Eq Rate standard, fast, and high-speed. It offers
– 53.32μAat 2.7V, Fast Mode, 8.2kHz Eq Rate programmable resolution of 8 or 12 bits to
Enhanced ESD Protection for IEC Testing: accommodate different screen sizes and performance
needs.
– ±8kV HBM The TSC2017 is available in a 12-lead,
(1.555 ±0,055mm)x (2.055 ±0,055mm),3x4 array, wafer chip-scale package (WCSP). The TSC2017is characterized for the –40°C to +85°C industrial
