MS6713 MOSA 3 Stereo Inputs / 4-Channel Outputs Audio Processor 3 Stereo Inputs and 4-Channel Outputs Volume, Tone, Balance, Fader, Loudness, and Selectable Input Gain FEATURES APPLICATIONS •Operation range : 2.7V~6.5V •3 stereo inputs with selectable input gain •4 independent speaker controls for fader and balance •Tone controls (treble and bass) and loudness function •Independent mute function •Volume control in 1.25 dB/step •I2C interface •Components less and good PSRR •Housed in SOP28, SSOP28 packages •Portable audio device •Car stereo audio •Hi-Fi audio system •Cross-reference: TDA7313 DESCRIPTION The MS6713 is a 3 stereo inputs/4-channel outputs digital control audio processor for the low voltage operation. Volume, tone (bass and treble), balance (left/right), and fader (front/rear) processor are incorporated into a single chip. The MS6713 also has the loudness function and selectable input gain. These functions can be built a Hi-Fi audio system easily. All functions are programmable via the serial I2C bus. The default states of the chip as the power is on are: the volume is -78.75dB, the stereo 4 is selected, all the speakers are mute and the gains of the input stage, the bass and the treble are 0dB. The stereo 4 is connected internally, but not available on pins.

The stop condition is activated when SCL is set to HIGH and SDA shifts from LOW to HIGH state. Please refer to the timing diagram below. SCL SDA Stop Start SCL : Serial Clock Line, SDA : Serial Data Line Data Validity A data on the SDA line is considered valid and stable only when the SCL signal is in HIGH state. The HIGH and LOW states of the SDA line can only change when the SCL signal is LOW. Please refer to the figure below. SDA SCL Data line stable, Data valid Data change allowed Byte Format Every byte transmitted to the SDA line consists of 8 bits. Each byte must be followed by an acknowledge bit. The MSB is transmitted first. Acknowledge During the Acknowledge clock pulse, the master (up) put a resistive HIGH level on the SDA line. The peripheral (audio processor) that acknowledges has to pull-down (LOW) the SDA line during the Acknowledge clock pulse so that the SDA line is in a stable LOW state during this clock pulse. Please refer to the diagram below. SCL 1 2 3 7 8 9 SDA MSB Acknowledge Start The audio processor that has been addressed has to generate an Acknowledge after receiving each byte, otherwise, the SDA line will remain at the HIGH level during the ninth (9th) clock pulse. In this case, the master transmitter can generate the STOP information in order to abort the transfer.
