I have project to work with RC522. Whether i should go for PIC LF series due to 3.3V issue. |

Honestly, these days, the most powerful PIC's are 3.3v, and more peripherals are 3.3v, than 5v.
It is perfectly possibly to use a 5v PIC with the 522, by adding suitable buffers, but why would you want to?. The only worthwhile reason would be that you have something more complex to drive, that is specifically 5v. Going 3.3v, also means only one supply needed. |

Just to be clear, many (most?) of the F-series 5V PICs are capable of working at 3.3V also. |
