PSoC 62 landing page https://www.cypress.com/documentation/datasheets/psoc-6-mcu-psoc-62-datasheet-programmable-system-chip-psoc 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_documents (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?
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).
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?
