TEA5764HN
FM radio + RDS
When the TEA5764HN is addressed by the FM radio address, the RDS part (byte12R to
byte27R) can be read in one read action. A read does not have to stop at byte11R.
Therefore, by effectively only using the RDS part of the address, ignores some bytes
which reduces I
2
C-bus access.

Structure of the I

Remark:
The I
2
C-bus operates at a maximum clock rate of 400 kHz. It is not allowed to
connect the TEA5764HN to a I
2
C-bus operating at a higher clock rate.
Data transfer to the IC:
Bit 7 of each byte is considered the MSB and has to be transferred as the first bit of
the byte
The LSB indicates the write or read action
The data becomes valid byte-wise at the appropriate falling edge of the SCL clock
A STOP condition after any byte can shorten transmission times. When writing to the
transceiver by using the STOP condition before completion of the whole transfer:
–
The remaining bytes will contain the old information
–
If the transfer of a byte is not completed the new bits will be used, but a new tuning
cycle will not be started
