PT2313L
DESCRIPTION
PT2313L is a four-channel digital control audio processor utilizing CMOS technology. Volume, Bass,
Balance, Front/Rear Fader Processor, Selectable Input Gain are incorporated into a single chip having
the highest performance and reliability with the least external components. All functions are
programmable using the I2C Bus. PT2313L is housed in 20-pin or 28-pin DIP/SOP package. The
28-pin version provides additional Two Band Tone Control and Loudness Function and is pin-to-pin
compatible with TDA7313. Pin assignments and application circuits are optimized for easy PCB layout
and cost saving advantages.

I2C BUS INTERFACE FUNCTION DESCRIPTION
BUS INTERFACE
Data are transmitted to and from the microprocessor to the PT2313L via the DATA and CLK. The
DATA and CLK make up the BUS Interface. It should be noted that the pull-up resistors must be
connected to the positive supply voltage.
DATA VALIDITY
A data on the DATA Line is considered valid and stable only when the CLK Signal is in HIGH State. The
HIGH and LOW States of the DATA Line can only change when the CLK signal is LOW. Please refer to
the figure below.
DATA
CLK
DATA LINE
STABLE,
DATA VALID
DATA

ALLOWED
START AND STOP CONDITIONS
A Start Condition is activated when
1. the CLK is set to HIGH and
2. DATA shifts from HIGH to LOW State.
The Stop Condition is activated when
1. CLK is set to HIGH and
2. DATA shifts from LOW to HIGH State.
Please refer to the timing diagram below.

PT2313L
BYTE FORMAT
Every byte transmitted to the DATA 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 (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
Acknowledge Clock Pulse so that the DATA Line is in a Stable Low State during this Clock Pulse.
Please refer to the diagram below.

F ROM RECEIV ER
START
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.

I2C BUS INTERFACE START TIME
After Power is turned ON, PT2313L needs to wait for a short time in order to insure stability. This
waiting period is relative to the value of Cref. As the Cref value is 10µf, the waiting time period for
PT2313L to send I2C Bus Signal is at least 300ms. If the waiting time period is less than 300ms, I2C
Control may fail. Please refer to the diagram below.

Notes:
1. For the Bass and Treble Response, please, refer to the diagram below. The center frequency and
quality of the resonance behavior can be selected by the external circuitry. A standard first order

2. The selected input is grounded thru the 2.2µF capacitor.

Notes:
1. Dimensioning and tolerancing per ANSI Y14.5M-1982.
2. Dimensions in inches (angles in degrees)
3. Dimension D does not include mold flash, protrusions or gate burrs. Mold flash, protrusions or gate
burrs shall not exceed 0.006” per end. Dimension E1 does not include interlead flash or protrusions.
Interlead flash or protrusions shall not exceed “0.006” per side. D1 and E1 dimensions are
determined at dutum H.
4. The package top may be smaller than the package bottom. Dimensions D and E1 are determined at
the outermost extremes of the plastic body exclusive of mold flash, tie bar burrs, gate burrs and
interlead flash, but including any mismatch between the top and bottom of the plastic.
5. Datums A and B to be determined at datum H.
6. N is the maximum number of terminal position. (N=20)
7. The dimensions apply to the flat section of the lead between 0.004 to 0.010 inches from the lead tip.
8. Dimension b does not include dambar protrusion. Allowable dambar protrusion shall be 0.004” total
in excess of b dimension at maximum material condition. The dambar can not be located on the
lower radius of the foot.
9. Refer to JEDEC MO-137 variation AD.
