Note The WUSB-NL radio module provided with CY3668 Rev. *A does not require these modifications.

CAUTION

• ANY CHANGE TO THE MODULE HAS TO BE CARRIED OUT BY A PERSON QUALIFIED IN REPLACING CHIP COMPONENTS.
• USE ESD PROTECTION WHILE CARRYING OUT THE MODIFICATION.
• USE TEMPERATURE-CONTROLLED SOLDERING STATION (RECOMMENDED).

INSTRUCTIONS TO MODIFY WUSB-NL MODULES
Perform the following changes on both the WUSB-NL modules:

• Replace the existing capacitor at location C7 with a 33-pF, 0603 size capacitor
• Replace the existing capacitor at location C8 with a 27-pF, 0603 size capacitor

Figure 1. WUSB-NL Module and Location of C7 and C8

Cypress recommends the following parts from Murata for this purpose:

• 33-pF capacitor : GRM1885C1H330JA01D
• 27-pF capacitor : GRM1885C1H270JA01D

After you complete these changes, the WUSB-NL modules are ready to interoperate with any nonDVK hardware.

INTEROPERATING WITH NON DVK WUSB-NL HARDWARE

For a modified WUSB-NL module to interoperate with nonDVK hardware, the firmware running on both hardware must be compatible.For this reason you must port the WUSB-NL driver provided with CY3668 Rev. ** to the nonDVK hardware before initiating data communication between them. If your application requires AgileHID protocol, you must port the AgileHID protocol provided with CY3668 Rev. ** DVK to the nonDVK hardware as well. Alternatively, you can also port the firmware (WUSB-NL driver and AgileHID protocol) running on the nonDVK hardware to CY3668 Rev. ** DVK.

For best operation, design the product so that the main antenna radiation is away from the body or at least not proximity-loaded by the human body or dielectric objects within the product.

Remember to keep the antenna away from clock lines, digital bus signals, and power supply; otherwise, harmonics of the clock frequency will jam certain receive frequencies.

•  RF path: Adhere closely to the recommended reference design circuit (Refer TRM, FIGURE-3.1)
•  Clock traces: Keep the quartz crystal traces simple and direct. The self-bias resistor should be close to the XTALi and XTALo pins. The oscillation loop, consisting of the series resistor and crystal, should be a simple, small loop. The crystal-loading capacitors should be near the crystal. The ground connection to these capacitors must be good, clean, and quiet. This prevents noise from being injected into the oscillator. It is best to have one ground plane for the entire RF section. Do not keep any unwanted trace below the crystal. The crystal and the associated components should be kept as close as possible to the IC pins (XTALOUT and XTALIN) to keep stray capacitance as minimum.
•  Power distribution and decoupling: Capacitors should be located near the VDD pins, as shown in Typical Application on page 13 of the WUSB-NL TRM.
•  Antenna placement: When using an antenna, follow the manufacturer's recommendation regarding layout.
•  Digital interface: The digital interface should be routed with a solid ground reference, to have a good return path you need a good grounding between RF and MCU that can help reduce noise 'seen' at the antenna, thus improving performance.

However, you can make the two radio modules compatible by replacing the passives C7 and C8 on the radio module provided with the Rev. ** kit. For more information on how to do this modification, see KBA83288.

Note: You can identify the CY3668 kit revision by the sticker attached behind the kit box. Similarly, you can identify the radio module provided with the CY3668 Rev *A kit by the sticker attached behind the module.

The following table lists Cypress’s wireless mouse portfolio. Based on the required features of the solution, the relevant products can be chosen for the design.

1. Button Bind
   In this type of binding, a separate bind button is provided for dongle and device. Binding takes place once the bind button is pressed on both dongle and device side. At the end of binding device stores unique ID of dongle in the flash. On subsequent power-on, device uses the stored unique ID of dongle for data transfer. Bind button can be used again to bind a different evice to the same dongle or vice versa.

   Advantage	Disadvantage
   Possibility of device wrongly binding to a different dongle is very less.	Increase in cost due to additional hardware circuitry needed for bind switch on both device and dongle. It is difficult to provide a bind switch in nano-dongle.

2. Power Bind
   In this type of binding there will not be a separate bind button in dongle or device. After power on, dongle goes to bind state if both keyboard and mouse are not bound. If one of the devices is bound then dongle will be in bind state for a period of 8 (configurable) sec and then move to Operating/Idle state. Once device is in Operating/Idle state, no device can be bound. To bind again, dongle power needs to be reset.
   Power bind con be made conditional too. In this case, it will go to binding mode on power on only if some condition (for example, a set of buttons pressed concurrently) is met.

   Advantage	Disadvantage
   No additional hardware circuitry required resulting in reduced cost. Simple to implement. If manufacturer wants to associate a dongle to a single device (like mouse) then binding is same as enhanced KISS bind.	If dongle is bound only to one device and if second device required to be bound then power to dongle needs to be reset. This would cause inconvenience to user.

3. Factory set Bind
   For factory set binding, unique ID of Dongle is read from PC using proprietary tool and stored in device flash. Device by default will be bound with specific dongle.

PRoC LP Mouse - The RDK mouse is a three-button optical mouse with scroll wheel. Based on the CYRF69103 PRoC LP for Peripherals and the Avago 3040 optical sensor.

SAN JOSE, Calif., October 16, 2012, – Cypress Semiconductor Corp. (NASDAQ: CY) today introduced a single-chip solution that integrates a wireless radio with touch-sensing circuitry for wireless mice, trackpads, remote controls, presenter tools, and other Human Interface Devices (HIDs). The new PRoC™-UI (Programmable Radio-on-a-Chip–User Interface) solution combines 2.4-GHz proprietary WirelessUSB™-NL Radio with Cypress’s CapSense® and TrueTouch® capacitive touch technologies. This combination enables user interface functionality in wireless devices, including gestures supported by the upcoming Windows 8 applications.

The one-chip solution also offers standard HID microcontroller functionality, effectively combining three chips into one to save BOM cost, board space, and power, while increasing reliability compared with multi-chip implementations. More information on the new device is available at www.cypress.com/go/PRoC-UI.

Cypress’s CapSense technology has replaced over 4 billion mechanical buttons worldwide, making Cypress the industry’s leading capacitive touch supplier. CapSense offers stylish interfaces, and superior reliability compared to mechanical buttons. PRoC-UI is also available with Cypress’s leading TrueTouch touchscreen technology, enabling multiple new HID use cases with multi-finger gesture recognition, including new Windows 8 gestures. The TrueTouch variant also supports customized gestures. Both CapSense and TrueTouch variants include advanced features such as proximity sensing (which allows a device to “wake up” as a hand approaches) and haptics (to give tactile user feedback).

PRoC-UI boasts an impressive -87 dBm receive sensitivity at 1 Mbps. This enhanced sensitivity enables longer range (up to 30 meters) operation and allows for lower-power transmit signals. The device features low active and standby currents, which enable longer battery life. It also offers superior performance in the presence of 2.4-GHz interference from common sources such as WiFi, Bluetooth, cordless phones, and microwaves.

“We are seeing an emerging class of applications and use cases that combine touch with wireless functionality. Cypress has integrated its market-leading user interface and wireless technologies to respond to this need,” said Jayant Somani, senior director of worldwide marketing for Cypress’s Data Communication Division. “The PRoC-UI solution delivers cost savings through integration, shorter design times, lower power, and smaller form factor. Perhaps more importantly, it allows our customers to differentiate their products in a highly competitive space.”

PRoC-UI supports Cypress’s AgileHID™ protocol that allows existing WirelessUSB-NL customers to get started quickly on their designs without any additional effort. Customers who have existing designs with WirelessUSB-NL can reuse the same dongles for new PRoC-UI based touch products. PRoC-UI comes with free software to enable end-product customization.

If you have any doubts as to whether your application can be supported with PRoC-EMB please contact procui@cypress.com.

Thus in the case of PRoC-CS (40 pin) you have 7 general purpose I/Os free for capacitive buttons in your design if you want to use the radio. The 7 I/Os can be used to support a maximum of 12 buttons using a matrix layout or it can be used to support a maximum of 14 segments on a capacitive slider using a diplexer. The 68 pin PRoC-CS part has 35 GPIOs (26 for capacitive sensing) and can be used for applications where there is a need for larger number of GPIOs.

The PRoC-TT part supports 35 general purpose I/Os that can be used for capacitive sensing. If you are using the radio, a maximum of 26 XY sensors are available for touch support.

In some cases your design may require more general purpose I/Os (GPIOs) than available on the PRoC-UI parts. An example of a design like this is a keyboard with a built-in trackpad.In such cases PRoC-UI supports connection of an external MCU over SPI. In the case of the keyboard with built in trackpad, the external MCU can handle mechanical buttons while the PRoC-UI can handle the trackpad and radio functionality.

We recommend the enCoRe Low Voltage series of MCUs for use with PRoC-UI. To find out more about our enCoRe low voltage MCUs please click here

PRoC-CS is enabled by SmartSense™ technology for auto tuning, which automatically optimizes CapSense® performance in a wide range of applications. The EMC version of SmartSense boasts of best in class noise immunity.

PRoC-TT, PRoC-USB, and PRoC-EMB are not intended for CapSense and thus do not support auto-tuning for capacitive sensors.

 PRoC-CS (CYRF89435-68LTXC) and PRoC-EMB (CYRF89135-40LTXC) will be supported in later releases of PSoC Designer.

Please contact procui@cypress.com to know more about this.

PRoC-CS (CYRF89435-68LTXC) and PRoC-EMB (CYRF89135-40LTXC) will be in production in the first quarter of 2013.

Please contact your local sales or procui@cypress.com for more details.

This application note discusses the necessary information for you to use a WirelessUSB(TM) LP radio in a product intended for the Japanese market. WirelessUSB based systems require a certification to market the product to make certain that it meets international regulations and national laws. This application note serves as a reference point in selecting WirelessUSB LP Radio for your application needs. The use of a Cypress radio chip and its suitability for Japanese product development is demonstrated by providing the compliance data on a reference development kit.

Wireless products are now found in abundance, all around us today, and their usage continues to rapidly expand. This application note introduces the Cypress CYRF8935 device and a sample PCB design. The appendix section guides you on antenna selection process.

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 note describes parameters that can affect WirelessUSB system performance. It also explains how to evaluate these parameters within your own wireless product design.

• One PRoC Development Module
• Two 12V Power Supplies
• Wire Kit (2" jumper wires and 1K ohm resistors)
• FlexPOD emulator cable
• CD-ROM containing:
  • Schematics
  • Example source code
  • Development tools

The CY3653 examples were built using PSoC Designer v4.2 with Service Pack 2, both of which are available for download separately from the Cypress website.

 If this modified circuit is not desirable and you want to program the PRoC without isolating the RF section, you can use Miniprog 3. Miniprog 3 supports Power cycle programming at 3.3V. Since the RF section is tolerant to voltages below 3.6V, 3.3 V programming by Miniprog 3 is acceptable.

To fix this, please add "ljmp Sleep_ISR" to line 131 of BOOT.ASM, or overwrite the existing BOOT.ASM with the attached one.

Hence, the radio chip needs some check over the current.
