PT2315A
DESCRIPTION
PT2315A is a two-channel digital audio processor utilizing CMOS Technology. Volume, Bass, Treble
and Balance Controls are incorporated into a single chip. Loudness Function is also provided to build a
highly effective electronic audio processor having the highest performance and reliability with the least
external components. All functions are programmable using the I2C Bus. The pin assignments and
application circuit are optimized for easy PCB layout and cost saving advantage for audio application.
Housed in a 20-pin DIP and SOP, PT2315A is pin-to-pin compatible with TDA7315 and is very similar
in performance with the later.

BYTE FORMAT
Every byte transmitted to the DATA Line consist 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 (µP) puts a resistive HIGH level on the DATA Line.
The peripheral (audio processor) that acknowledges has to pull-down (LOW) the DATA line during the
www.DataSAhecekt4nUo.cwomledge Clock Pulse so that the DATA Line is in a Stable Low State during this Clock Pulse.
Please refer to the diagram below.

AC KNOWLED GE MENT
FROM RECE IV ER
The audio processor that has been addressed has to generate an acknowledge after receiving each
byte, otherwise, the DATA 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.
TRANSMISSION WITHOUT ACKNOWLEDGE
If you want to avoid the acknowledge detection of the audio processor, a simpler µP transmission may
be used. Wait one clock and do not check the slave acknowledge of this same clock then send the new
data. If you use this approach, there are greater chances of faulty operation as well as decrease in
noise immunity.
INTERFACE PROTOCOL
The interface protocol consists of the following:
• A Start Condition
• A Chip Address Byte including the PT2315A address. The 8th Bit of the Byte must be “0”. PT2315A
must always acknowledge the end of each transmitted byte.
• A Data Sequence (N-Bytes + Acknowledge)
• A Stop Condition
