I
2
C-bus interface
An I
2
C-bus (Inter-IC) interface is supported to enable a low-cost, low pin count serial bus
interface to the host. The I
2
C-bus interface is implemented according to
NXP Semiconductors’
I
2
C-bus interface specification, rev. 2.1, January 2000
. The
interface can only act in Slave mode. Therefore the MFRC522 does not implement clock
generation or access arbitration.
The MFRC522 can act either as a slave receiver or slave transmitter in Standard mode,
Fast mode and High-speed mode.
SDA is a bidirectional line connected to a positive supply voltage using a current source or
a pull-up resistor. Both SDA and SCL lines are set HIGH when data is not transmitted. The
MFRC522 has a 3-state output stage to perform the wired-AND function. Data on the
I
2
C-bus can be transferred at data rates of up to 100 kBd in Standard mode, up to
400 kBd in Fast mode or up to 3.4 Mbit/s in High-speed mode.
If the I
2
C-bus interface is selected, spike suppression is activated on lines SCL and SDA
as defined in the I
2
C-bus interface specification.

Table 155 on page 76
