An Inter IC (I
interface to the host. The implemented I
Semiconductors I
interface can only act in Slave mode. Therefore no clock generation and access
arbitration is implemented in the MFRC522.
The implemented interface is conform to the I
January 2000. The MFRC522 can act as a slave receiver or slave transmitter in Standard
mode, Fast mode and High-speed mode.
SDA is a bi-directional line, connected to a positive supply voltage via a current-source or
a pull-up resistor. Both lines SDA and SCL are set to HIGH level if no data is transmitted.
The MFRC522 has a tri-state output stage to perform the wired-AND function. Data on the
