DESCRIPTION
The TDA7430/TDA7431 is volume tone (bass middle
and treble) balance (Left/Right) processors voice
canceller for quality audio applications in car radio
and Hi-Fi systems.
– 2 INDEPENDENT SPEAKERS AND 2 INDEPENDENT RECORD CONTROL
IN 1dB STEP FOR BALANCE FACILITY
They reproduce surround sound by using programmable phase shifters and a signal matrix.
– AVAILABILITY OF LOUDSPEAKER EQUALIZATION FIXED BY EXTERNAL COMPONENTS
Control of all the functions is accomplished by serial bus. The AC signal setting is obtained by resistor networks and switches combined with
operational amplifiers. Thanks to the used BIPOLAR/CMOS Technology,
– INDEPENDENT MUTE FUNCTION
■
TQFP44
ALL FUNCTIONS PROGRAMMABLE VIA
SERIAL BUS
Low Distortion, Low Noise and DC stepping are
obtained.

I2C BUS INTERFACE
Data transmission from microprocessor to the TDA7430/TDA7431 and viceversa takes place through the 2
wires I2C BUS interface, consisting of the two lines SDA and SCL (pull-up resistors to positive supply voltage
must be connected).
3.1 Data Validity
As shown in fig. 8, 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.
3.2 Start and Stop Conditions
As shown in fig.9 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 transition of the SDA line while SCL is HIGH.
3.3 Byte Format
Every byte transferred on the SDA line must contain 8 bits. Each byte must be followed by an acknowledge bit.
The MSB is transferred first.
3.4 Acknowledge
The master (µP) puts a resistive HIGH level on the SDA line during the acknowledge clock pulse (see fig. 10).
The peripheral (audioprocessor) that acknowledges 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 reception 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 generate the STOP information in order to abort the transfer.
3.5 Transmission without Acknowledge
Avoiding to detect the acknowledge of the audioprocessor, 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.

4.1 Interface Protocol
The interface protocol comprises:
■
A start condition (S)
■
A chip address byte, containing the TDA7430/TDA7431 address
■
A subaddress bytes
■
A sequence of data (N byte + achnowledge)
■
A stop condition (P)

EXAMPLES
5.1 No Incremental Bus
The TDA7430/TDA7431 receives a start condition, 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.

5.2 Incremental Bus
The TDA7430/TDA7431 receives a start condition, 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.
