SBAS415C – JUNE 2007 – REVISED MARCH 2009 1.2V to 3.6V, 12-Bit, Nanopower, 4-Wire TOUCH SCREEN CONTROLLER with SPI™ Interface • Personal Digital Assistants 23 • 4-Wire Touch Screen Interface • Cellular Phones • Ratiometric Conversion • Portable Instruments • Single 1.2V to 3.6V Supply • Point-of-Sale Terminals • Preprocessing to Reduce Bus Activity • MP3 Players, Pagers • High-Speed SPI-Compatible Interface • Multiscreen Touch Control Systems • Internal Detection of Screen Touch • Register-Based Programmable: – 10-Bit or 12-Bit Resolution The TSC2006 is a very low-power touch screen – Sampling Rates controller designed to work with power-sensitive, handheld applications that are based on advanced – System Timing low-voltage processors. It works with a supply voltage • On-Chip Temperature Measurement as low as 1.2V, which can be supplied by a • Touch Pressure Measurement single-cell battery. It contains a complete, • Auto Power-Down Control ultralow-power, 12-bit, analog-to-digital (A/D) resistive touch screen converter, including drivers and the • Low Power: control logic to measure touch pressure. – 707 µW at 1.8V, 50SSPS In addition to these standard features, the TSC2006 – 544 µW at 1.6V, 50SSPS offers preprocessing of the touch screen – 280 µW at 1.2V, 50SSPS measurements to reduce bus loading, thus reducing – 69 µW at 1.6V, 8.2kSPS Eq. Rate the consumption of host processor resources that can then be redirected to more critical functions. – 43 µW 1.2V, 8.2kSPS Eq. Rate The TSC2006 supports an SPI-compatible serial bus • Enhanced ESD Protection: up to 25MHz. It offers programmable resolution of 10 – ±8kV HBM or 12 bits to accommodate different screen sizes and – ±1kV CDM performance needs. – ±25kV Air Gap Discharge The TSC2006 is available in a miniature 20-lead, – ±12kV Contact Discharge 4 × 4 QFN package, and is characterized for the –40°C to +85°C industrial temperature range. • 4 × 4 QFN-20 and 0.4mm 4 × 4 XTQFN-20(1) Packages (1) XTQFN package available Q4, 2009.
