Analog Matrix Touch Screen Controller 32-Pin WQFN EP T/R

The TSC2020 is a very low power, resistive touch screen power-sensitive, handheld applications that are based on advanced low-voltage processors. This device works with a supply voltage as low as 1.6V that can be supplied by a single-cell battery. The TSC2020 contains analog-to-digital converter (ADC) including sensor drivers and the control logic to measure touch pressure. controllers, the TSC2020 is capable of detecting at least three touches simultaneously and delivers a very low power standby touch detection scheme. This flexibility allows for many new applications that require multiple touches but must remain at low powerThe TSC2020 supports the I transmission protocol for all three defined modes: standard, fast, and high-speed. The TSC2020 offers programmable resolution, single-/multi-touch modes to accommodate different screen types, sizes, and application needs.The TSC2020 is available in a 32-pin 5 × 5 QFN package, and is characterized for the –40°C to +85°C industrial temperature range
