Hello,

I was trying to build a small board for a BGA124 PSoC62 device (CY8C6246BZI-D04). I assumed initially all the PSoC 62 in the BGA124 package would have the same pinout, but I'm not so sure now... in fact I'm not 100% sure of the correct pinout for this part itself. I haven't gone through every pin, but balls K1/K2/K3 were how I first noticed the problem.

PSoC 62 landing page https://www.cypress.com/documentation/datasheets/psoc-6-mcu-psoc-62-datasheet-programmable-system-ch...  points me to the datasheet at https://www.cypress.com/file/385916/download  .

K1 = VRF

K2 = VIND2

K3 = VBUCK2

Another datasheet at https://www.cypress.com/file/460816/download had this pinout:

K1 = NC

K2 = VIND2

K3 = VIND2

According to the symbol at https://www.cypress.com/cad-resources/cad-library-psoc-6-mcu-family?source=search&cat=technical_docu... (which lists CY8C6246BZI-D04) as one of them this symbol supports:

K1 = K2 = K3 = NC

This also follows the schematic of the CY8CMOD-062-4343W (which I assume is ‘ground truthed’ then) that shows no connection to these pins.

Was this a revision change? It seems the pins in question can be left NC (since I don't need those features), but wanted to confirm.

Thanks,

-Colin

Colin,

PSoC 62 landing page https://www.cypress.com/documentation/datasheets/psoc-6-mcu-psoc-62-datasheet-programmable-system-ch...  points me to the datasheet at https://www.cypress.com/file/385916/download  .

K1 = VRF

K2 = VIND2

K3 = VBUCK2

This is correct.

Another datasheet at https://www.cypress.com/file/460816/download had this pinout:

K1 = NC

K2 = VIND2

K3 = VIND2

This datasheet is only for CY8C62x8/CY8C62xA family parts, so don't refer it.

According to the symbol at https://www.cypress.com/cad-resources/cad-library-psoc-6-mcu-family?source=search&cat=technical_docu... (which lists CY8C6246BZI-D04) as one of them this symbol supports:

K1 = K2 = K3 = NC

Could you please tell me which symbol file shows K1=K2=K3=NC, could you please tell me the file name?

Hello,

The symbol was the alitum symbol in that package - if you look at the PDF (PSOC_PARTS_PSOC6MCU.pdf) that includes the parts you will notice that package covers the original part in question. But it's the same symbol used in the schematic at https://www.cypress.com/file/457816/download - this schematic is for the CY8C624ABZI-D44 (so I guess refers to the other part).

Thanks,

-Colin

Yes, pins definition of CY8C62x8/CY8C62xA family parts is different with CY8C6246BZI-D04, even if the package is the same.

OK thanks for the details. So the pinout in the symbol library (and on schematic I linked) is incorrect then?

Yes.
