Cypress also supports WUSB-LP radio & PRoC-LP SoC based wireless HID solutions. These solutions have in-built power management unit & DSSS based exceptional interference immunity.
Design Considerations
Human interface devices (HID) are products that are used for human-PC interactions like mice, keyboards & presenters. HID devices are increasingly converting from wired to wireless. Wireless HID products offer extensive mobility & range without the hassle of connection wires (USB, PS/2, etc). They also free up USB ports as multiple wireless devices can connect to single dongle; thus using only 1 USB port in contrast to 1 each for every wired device.
Even with all the additional benefits, wireless HID products have to be cost competitive with wired ones. This makes the cost of solution a very important factor. Also, features like multi-year battery life, low battery indication & superior inference immunity are becoming standard features on the products; and these must be supported without increasing solution cost.
To serve the current & future needs of the market, Cypress has a strong portfolio of HID solutions. The portfolio consists of HID optimized MCU & radio products. The solutions offer a battery life of up to 3 years and reduction in BOM cost by supporting bare die on PCB (chip-on-board). The solution is complemented by the mature & field proven AgileHID® protocol that ensures best in class interference immunity.
Application Notes
-
When product designers use reference designs as a basis for their own projects, they typically modify or enhance the original designs. Unfortunately, these modifications can cause a considerable decline in performance.
-
This application notes discusses avoiding interference using WirelessUSB.
-
AN5033 describes the guidelines for the antenna design and in particular, addresses the design of an integrated printed trace wiggle antenna implementation on a reference printed circuit board (PCB).
-
AN60685 describes a firmware project that bridges powerline communication (PLC) across different electrical phases using an Artaflex AWP24S CyFi™ radio frequency (RF) module. This wireless phase-coupler application works with the Cypress PLC solution’s network protocol. The project for the CY8CPLC20 is attached.
