TDA7429S TDA7429T
DIGITALLY CONTROLLED AUDIO PROCESSOR WITH SURROUND SOUND MATRIX
3 STEREO/4 STEREO INPUTS INPUT ATTENUATION CONTROL IN 0.5dB STEP TREBLE MIDDLE AND BASS CONTROL THREE SURROUND MODES ARE AVAILABLE: - MUSIC: 4 SELECTABLE RESPONSES - MOVIE AND SIMULATED: 256 SELECTABLE RESPONSES FOUR SPEAKERS ATTENUATORS: - 4 INDEPENDENT SPEAKERS CONTROL IN 1dB STEPS FOR BALANCE FACILITY - INDEPENDENT MUTE FUNCTION ALL FUNCTIONS PROGRAMMABLE VIA SERIAL BUS DESCRIPTION The TDA7429 is volume tone (bass middle and treble) balance (Left/Right) processors for quality audio applications in TV and Hi-Fi systems. PIN CONNECTION (TQFP44)

TQFP44
ORDERING NUMBERS: TDA7429S TDA7429T
It reproduces surround sound by using programmable phase shifters and a signal matrix. 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, Low Distortion, Low Noise and DC stepping are obtained.

I C BUS INTERFACE Data transmission from microprocessor to the TDA7429 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). 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 transition of the SDA line while SCL is HIGH. Byte Format Every byte transferred on the SDA line must contain 8 bits. Each byte must be followed by an acFigure 3: Data Validity on the I2CBUS

knowledge bit. The MSB is transferred first. Acknowledge The master (P) puts a resistive HIGH level on the SDA line during the acknowledge clock pulse (see fig. 5). 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. Transmission without Acknowledge Avoiding to detect the acknowledge of the audioprocessor, the P 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.

SOFTWARE SPECIFICATION Interface Protocol The interface protocol comprises: A start condition (S) A chip address byte, containing the TDA7429 address A subaddress bytes A sequence of data (N byte + achnowledge) A stop condition (P)
CHIP ADDRESS MSB S 1 0 0 0 0 0 A LSB 0 ACK MSB B
SUBADDRESS LSB DATA ACK MSB
DATA 1 to DATA n LSB DATA ACK P
D95AU226A
ACK = Achnowledge S = Start P = Stop A = Address B = Auto Increment
EXAMPLES No Incremental Bus The TDA7429 receives a start condition, the cor-
rect chip address, a subaddress with the MSB = 0 (no incremental bus), N-datas (all these datas concern the subaddress selected), a stop condition.

D95AU306
Incremental Bus The TDA7429 receive s 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.
