The PSoC provides a one-chip solution for majority of the home appliances integrating CapSense which is industry’s best touch solution, analog sensor interface to interface various sensors for humidity temperature measurement, LED and LCD drivers for output user interface.PSoC also helps integrating other system functions like RTC, relay, motor, LED backlight, buzzer control using on-chip resources.Communication interfaces can be selected from a rich list of supported protocols by PSoC that helps communicating with host-controllers in large appliances or interfacing with external peripherals like digital sensors etc.

Design Considerations

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.

  1. 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.
  2. 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
  3. 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

アプリケーション

The induction subsystem includes a heatproof ceramic panel, which is used as the cooker plane.Through the electrified coil under the plane, the AC current creates a magnetic field that induces a vortex in iron and stainless steel pan bottom.This heats the pan bottom quickly, and then conducts the heat to food...
