I'm looking at the datasheet for this part, Document Number: 002-23053 Revised Feb 22, 2018.

The BGA footprint on page 42 shows pins H8, J8, J5 and J4 removed.

The Pin List for WLCSP (BGA) is shown in Table 2 on Page 12.

B1 is shown as NB (No Ball)

H8 is shown as ANT

J4 is shown as VDDR

J8 is shown as NO CONNECT (Not NB or No Ball like B1)

J6 has no pin description

Looking at PSOC Creator Pins definition for this part:

B1 is shown as P2[3]

J7 is shows as NC

J4, J5, J8 and J9 pins are removed

Which information is correct?

What does the datasheet mean by No Connect (NC). Does this mean the pin is not connected to circuitry inside the package, or does it mean the designer should not connect any circuitry to this pin?

Regards,

John

Hello John

Thank you for your interest in Cypress products. We have forwarded your query to our product development team, who will evaluate your query.

The No connection pins means that there is no internal connection to the pins. These have been included to provide the ICs in standard packaging. These pins should not be used while designing any application.

Thank you

Best regards

Looking at page 41, it appears as though the pin list table is referring to the 256K BLE package. Hence the reason why B1 is removed, J5, J6, J9 and H9 are removed. This should be fixed as this is not clear.

I still have the question about NC pins.
