We are tapping into the appliance revolution where homeowners want sophisiticated and elegant appliances. These products need to have capacitive buttons and slides, LCD or LED display. User want want flat surfaces that are easy to clean and buttons to be available in accesible locations in appliances. There are various challenges that you may face while designing for today’s market needs.
-
Capacitive buttons can be unreliable
Water droplets can cause false touches
Curved or thick overlays reduce button performance
Manufacturing variations require time-consuming re-tuning
EMI can cause buttons to malfunction
Class B safety certification is required.
-
Extra features add cost
Each UI system must have a host MCU and sensors
Each analog sensor requires an additional IC
Each additional IC raises BOM cost and design complexity
-
Your IP is vulnerable in a common MCU
Many websites offer reverse-engineering of MCU firmware

PSoC solves these problems
Cypress CapSense works under water droplets and detects touch through curved or thick overlays
SmartSense Auto-tuning = No manual tuning + Better EMI immunity
Cypress provides a Class B self-test library for safe operation
The PSoC one-chip solution integrates CapSense, analog sensor interfaces, LED and LCD drivers
PSoC encrypts IP in your systems, making it very difficult to reverse-engineer your IP
CapSense in PSoC is a one-chip, easy-to-use, low-cost UI solution with high reliability and IP protection
