MFRC500
Highly Integrated ISO/IEC 14443 A Reader IC
Remark:
It is recommended to use the Q-clock.
9.11 Serial signal switch
The MFRC500 comprises two main blocks:
digital circuitry:
comprising the state machines, encoder and decoder logic etc.
analog circuitry
: comprising the modulator, antenna drivers, receiver and
amplification circuitry
The interface between these two blocks can be configured so that the interface signals
are routed to pins MFIN and MFOUT. This makes it possible to connect the analog part of
one MFRC500 to the digital part of another device.
9.11.1
Serial signal switch block diagram
Figure 12
shows the serial signal switches. Three different switches are implemented in
the serial signal switch enabling the MFRC500 to be used in different configurations.
The serial signal switch can also be used to check the transmitted and received data
during the design-in phase or for test purposes.
Section 15.2.1 on page 94
describes the
analog test signals and measurements at the serial signal switch.
Remark:
The SLR400 uses pin name SIGOUT for pin MFOUT. The MFRC500
functionality includes the test modes for the SLRC400 using pin MFOUT.
