QT60645B

      The QT60645B is designed as 64-key QMatrix keypanel sensor IC with typical applications of automotive panels, machine tools, ATM machines, touch-screens, appliance controls, outdoor keypads, security keypanels and industrial keyboards.
      QT60645B has many features.The first one is it would have advanced second generation QMatrix controllers.The second one is that it would have up to 64 touch keys through any dielectric.The third one is that it would have panel thicknesses to 5 cm or more.The fourth one is that it would be 100% autocal for life - no adjustments required.The fifth one is keys individually adjustable for sensitivity, response time, and many other critical parameters.The sixth one is mix and match key sizes & shapes in one panel.The seventh one is passive matrix - no components at the keys.The eighth one is that it would be moisture suppression capable.The ninth one is that it would have AKS - Adjacent Key Suppression feature.The tenth one is synchronous noise suppression.The next one is sleep mode with wake pin.The next one is SPI Slave or Master/Slave interface to a host controller.The next one is that it would have low overhead communications protocol.The last one is that it would be 44-pin TQFP packaged.
      Some absolute maximum specifications of QT60645B have been concluded into several points as follow.The first one is about its operating temperature which would be from -40°C to +105°C.The second one is about its storage temperature which would be from -55°C to +125°C.The third one is about its Vdd which would be from -0.5 to +5.5V.The fourth one is about its max continuous pin current, any control or drive pin which would be ±10mA.The fifth one is about its short circuit duration to ground, any pin which would be infinite.The sixth one is about its short circuit duration to Vdd, any pin which would be infinite.The seventh one is about its voltage forced onto any pin which would be from -0.6V to (Vdd + 0.6) Volts.The eighth one is about its frequency of operation which would be 16MHz.The ninth one is about its eeprom maximum writes which would be 100,000 write cycles.The tenth one is about its flash maximum writes (eeprom backup) which would be 1,000 write cycles.
