MFRC522 connection support

akhilranga · ‎08-20-2022

hello there,

I am having trouble with figuring out the connection interface between my MFRC522 module and S32k144EVB.

My MFRC522module pin out is : SDA,SCK,MOSI,MISO,GND,3.3v

and the LSPI0 pinout is SCK,SIN,SOUT,PCS0.....PCS3

so help me figure out to connect which port to which.

Thank you

Hi,

from MFRC522 datasheet you can see

So the connection will be below
MCU - MFRC522
SCK - SCK
SOUT - MOSI
SIN - MISO
PCS0 - NSS
