Block Diagram - CapSense for Automotive Infotainment applications

Design Considerations
When designing capacitive touch sense technology into automotive, one needs to keep in mind that the CapSense device exists within a larger framework. Careful attention to every level of detail from PCB layout to user interface to end-use operating environment will lead to robust and reliable system performance.

Application Notes

AN2397 - PSoC® 1 and CapSense® Controllers – CapSense Data Monitoring Tools
AN2397 shows how to monitor CapSense data from PSoC 1 and CapSense controllers using the I2C or UART interface. With the tools described in this application note, you can view and log real-time sensor data for CapSense tuning and debugging.

AN59389 - Host Sourced Serial Programming for CY8C20xx6A, CY8C20xx6AS, CY8C20xx6L and CY8C20xx7/S
Host Sourced Serial Programming (HSSP) is a method of in-circuit serial programming (using ISSP protocol) of the CY8C20xx6A, CY8C20xx6AS, CY8C20xx6L and CY8C20xx7 devices from an onboard host processor. AN59389 explains how to use and port the HSSP code example, provided along with this application note, to the desired host processor for programming the CY8C20xx6A, CY8C20xx6AS, CY8C20xx6L and CY8C20xx7 devices.

Cypress's PSoC-based CapSense technology provides a flexible, efficient means for implementing highly differentiated and reliable capacitive sensing & proximity detection with a single chip for automotive infotainment systems. Around the globe, these innovations are making the driver experience safer and more intuitive. That’s why so many of the world’s leading vehicle OEMs and suppliers choose Cypress’s capacitive touch sensing  and proximity sensing solutions. CapSense allows for “cool” designs by replacing mechanical buttons with a sleeker, more refined interface for the car infotainment systems.

As market leader, Cypress makes it easy for designers to merge new features with pre-existing mechanical platforms for functionality enhancement and vastly improved touch based interfaces.
Our fully programmable CapSensing solution means full flexibility for the designers and the GUI that comes with our devices ensures ease of development.
Cypress Capacitive solutions ensure:

  • Superior noise immunity and low radiated noise,
  • Best in class CapSense performance with superior water proofing(on CSD),
  • Ease of development and full programmability,
  • Enabling integration through additional analog and digital peripherals on the same chip.

Typical applications include (but not limited to):
Center consoles, Rear seat entertainment systems, Over head Infotainment systems
