Hi, I am working on a security system and I am planning to use RFID chip MFRC522 and the micro-controller that will manage the communication with the RFID will be pic18F452, is this a right combination from the point of view of security?
Also, my friends told me that I should use chips from Atmel like "ATmega1284P" because of security issues and the pic18F452 could be hacked, is this right? and would you please recommend micro-controller for my case.
Hello,
As mentioned in the internal case:
Currently, the PNEV512B implements an LPC1769 for
controlling the NFC Front End.
PNEV512B is the evaluation board compatible with MFRC522
Front End for which the NFC Reader Library is compatible as well. This way you
can interface LPC1769 to MFRC522 through SPI, UART or I2C.
Otherwise, if you need a securer host MCU you can refer to LPC18Sxx
Family with security features for protecting code and data.
