Design Problems Engineers Face

1. Touch Sensing is difficult to implement in Wireless HID designsCurved or thick overlays reduce SNR performance

Radio emissions degrade SNR and cause false touches

Manufacturing variability requires time-consuming manual tuning

2. Typical implementation requires three ICs, adding cost and complexityA microcontroller for sensor control, LED control, battery monitoring, and radio control

An RF Transceiver for wireless communication

A special IC for Touch Sensing

Each additional IC increases BOM cost and design complexity

3. Wireless designs can be unreliableInterference from other wireless devices, such as WiFi routers, can cause false or missed touches

Traditional Approach and Challenges: To present the traditional approach and the challenges engineers will face when using it to realize the Market Vision. Ends with a one-sentence segue clearly stating the benefit of the Cypress solution.

PRoC-CS solves these problemsSmartSense optimizes SNR even for curved and thick overlays in noisy RF environments
