WLCSP Reference Design

[GuLi_1398161]

Hello,

   

In our application the 7x7mm QFN won't fit. We need to use the WLCSP version but we had difficulty finding any reference design using this package. Do you have a recommended design for this package that you can provide?

   

Are PSoC 4 BLE WLCSP and PRoC 4 BLE WLCSP pinouts identical/interchangeable?

Hi

       

Currently we don't have reference design for WLCSP package.

       

Both PSOIC4 BLE and PROC BLE WLCSP packages are pin-pin compatible .

       

You can refer the app notes

   

1)http://www.cypress.com/file/126296/download

   

2)http://www.cypress.com/file/136041/download

       

Though these are not specific to PSOC4 BLE/PROC BLE you can use them as a reference.

       

Once you are done with layout ,We recommend to create tech support case  https://secure.cypress.com/myaccount/?id=25&source=contactus to get it reviewed.
