SID 2011: Cypress' True Single Layer Sensor
John Carey from Cypress Semiconductor discusses the company's true single layer sensor, which can do both self-cap sensing and mutual cap sensing.
Cypress technology in devices like the TMA340 allows them to do both self capacitance and mutual capacitance measurements in the same device. This capability allows them to support advanced features like waterproofing, 1mm stylus and hover.
The release of single layer sensor is for the TST241 and TST242.
