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.





Cypress wireless solutions share the unique qualities of ultra-reliable, low-power, and are optimized for wireless HID applications.The product portfolio features a rich assortment of 2.4 GHz radios & 8-bit companion MCUs.
