MFRC523
Contactless reader IC
The address byte must meet the following formats:
the MSB of the first byte sets the mode used
–
the MSB is set to logic 0 to write data to the MFRC523
–
the MSB is set to logic 1 to read data from the MFRC523
bit 6 is reserved for future use
bits [5:0] define the address; see
Table 15
Table 15.
Bit 7
(MSB)
1 or 0

I
2
C Bus Interface
An I
2
C-bus interface is supported and enables implementation of a low-cost, low pin count
serial bus interface to the host. The I
2
C-bus interface is implemented based on
NXP Semiconductors’
I
2
C-bus interface specification, rev. 2.1, January 2000
. The
interface can only act in slave mode. Therefore the MFRC523 does not perform clock
generation or access arbitration.
The MFRC523 can act 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
MFRC523 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.
See
Table 156 on page 77
for timing requirements.
