It works with a supply voltage – TSC2003/TSC2007 Compatible as low as 1.6V, which can be supplied by a – 8- or 12-Bit Resolution single-cell battery. It contains a 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 logic to measure touch pressure. • Digital Buffered PENIRQ In addition to these standard features, the TSC2017 • On-Chip, Programmable PENIRQ Pull-Up offers preprocessing of the touch screen • Comprehensive Reset Schemes: measurements to reduce bus loading, thus reducing – Power-On, Software, and Hardware Resets the consumption of host processor resources that can then be redirected to more critical functions. • Auto Power-Down Control • Low Power (12-Bit): The TSC2017 supports I2C serial bus and data transmission protocol in all three defined modes: – 39.31 μA at 1.8V, Fast Mode, 8.2kHz Eq Rate standard, fast, and high-speed. It offers – 53.32 μA at 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 – ±1kV CDM The TSC2017 is available in a 12-lead, (1.555 ±0,055mm) x (2.055 ±0,055mm), 3 x 4 array, – ±25kV Air Gap Discharge wafer chip-scale package (WCSP). The TSC2017 is – ±15kV Contact Discharge characterized for the –40°C to +85°C industrial • 2.1 x 1.6 WCSP-12 Package temperature range.
