9.1.2.1 FeliCa framing and coding
9.1.2 FeliCa reader/writer functionality
The FeliCa mode is the general reader/writer to card communication scheme according to
the FeliCa specification. The following diagram describes the communication on a
physical level, the communication overview describes the physical parameters.
Table 132. Communication overview for FeliCa reader/writer
The contactless UART of PN512 and a dedicated external host controller are required to
handle the complete FeliCa protocol.
Table 133. FeliCa framing and coding
To enable the FeliCa communication a 6 byte preamble (00h, 00h, 00h, 00h, 00h, 00h)
and 2 bytes Sync bytes (B2h, 4Dh) are sent to synchronize the receiver.
The following Len byte indicates the length of the sent data bytes plus the LEN byte itself.
The CRC calculation is done according to the FeliCa definitions with the MSB first.
To transmit data on the RF interface, the host controller has to send the Len- and data-
bytes to the PN512's FIFO-buffer. The preamble and the sync bytes are generated by the
PN512 automatically and must not be written to the FIFO by the host controller. The
PN512 performs internally the CRC calculation and adds the result to the data frame.
Example for FeliCa CRC Calculation:
