DESCRIPTIONThe TDA7430/7431 are volume tone (bass middle
and treble) balance (Left/Right) processors with
voice canceller for quality audio applications in
car radio and Hi-Fi systems.
They reproduce surround sound by using pro-
grammable phase shifters and a signal matrix.
Control of all the functions is accomplished by se-
rial bus.
The AC signal setting is obtained by resistor net-
works and switches combined with operational
amplifiers.
Thanks to the used BIPOLAR/CMOS Technology,
Low Distortion, Low Noise and DC stepping are
obtained.

2 C BUS INTERFACEData transmission from microprocessor to the
TDA7430/TDA7431 and viceversa takes place
through the 2 wires I2 C BUS interface, consisting
of the two lines SDA and SCL (pull-up resistors to
positive supply voltage must be connected).
Data Validity
As shown in fig. 3, the data on the SDA line must
be stable during the high period of the clock. The
HIGH and LOW state of the data line can only
change when the clock signal on the SCL line is
LOW.
Start and Stop Conditions
As shown in fig.4 a start condition is a HIGH to
LOW transition of the SDA line while SCL is
HIGH. The stop condition is a LOW to HIGH tran-
sition of the SDA line while SCL is HIGH.
Byte Format
Every byte transferred on the SDA line must con-
tain 8 bits. Each byte must be followed by an ac-
knowledge bit. The MSB is transferred first.
Acknowledge
The master (μP) puts a resistive HIGH level on the
SDA line during the acknowledge clock pulse (see
fig. 5). The peripheral (audioprocessor) that ac-
knowledges has to pull-down (LOW) the SDA line
during this clock pulse.
The audioprocessor which has been addressed
has to generate an acknowledge after the recep-
tion of each byte, otherwise the SDA line remains
at the HIGH level during the ninth clock pulse
time. In this case the master transmitter can gen-
erate the STOP information in order to abort the
transfer.
Transmission without Acknowledge
Avoiding to detect the acknowledge of the audio-
processor, the μP can use a simpler transmission:
simply it waits one clock without checking the
slave acknowledging, and sends the new data.
This approach of course is less protected from
misworking.

EXAMPLES
No Incremental BusThe TDA7430 /TDA7431 receives a start condi-
tion, the correct chip address, a subaddress with
the MSB = 0 (no incremental bus), N-datas (all
these datas concern the subaddress selected), a
stop condition.

SUBADDRESS DATA
Incremental BusThe TDA7430 /TDA7431 receive s a start condi-
tion, the correct chip address, a subaddress with
the MSB = 1 (incremental bus): now it is in a loop
condition with an autoincrease of the subaddress
whereas SUBADDRESS from "1XXX1010" to
"1XXX1111" of DATA are ignored.
The DATA 1 concern thesubaddress sent, and
the DATA 2 concern the subaddress sent plus
one in the loop etc, and at the end it receivers the
stop condition.
