Power Save
LA73024AV has two supplies 5V for Video part and 12V for audio part and FSS output. LA73024AV separates
perfectly 5V system from 12V system, so it can be individually movement. For example when in the stand-by mode, if
you open 14 pins but 5V supplies 24 and 29 pins, Video part and serial control part work normally. In this case audio
part and FSS output don’t work normally. And when you pull up 8pin and open 24 pin , IC chooses automatically video
sw3-B.Consequently Ext input and Decoder output only move , you can save more power dissipation .
Audio Mute
LA73024AV builds in two mute transistors for reduce audio pop-noise when occur at power on and off. You can control
both on serial control and on external parallel control for audio mute.

Data transfer
I2C-BUS control system is adopted in SW IC and SW IC is controlled by SCL (Serial Clock) and SDA (Serial Data) At
first, please set up the START condition*1 by these two terminals (SCL and SDA). And next, please input the 8bits data
which should be synchronized with SCL into SDA terminal. Still more, please give priority to high rank bit at data
transfer order (MSB → LSB). The 9th bit is called as ACK (Acknowledge), SW IC sends [0] to the SDA terminal
during SCL [1] period. So, please open the port of micro-processor during this period. LA73026AV adopt
auto-increment, so you input only first sub-address data (called as Group) and you can transfer data in order. As thus
the Data transfer Stop condition*2 is finished.
*1
SDA rise up during SCI is [1]
*2
SDA fall down during SCL is [1]
No.A0239-9/13
LA73026AV
Transfer data format
The transfer data is composed by START condition, Slave address data*3, and STOP condition.
After setting up the START condition, please transfer the Slave Address (regulated as “10010100” in SW IC). Group
and next control data (Please see “Data structure”)
Slave Address is composed by 7bits, and this bit 8th bit*4 should be set as [0].
But SW IC is not equipped with such a data out function, please keep this bit as [0].
The both of Group data and control data are composed by 8bits, and the one control action is defined with combination
of these two data. And if you want to control 2 or more groups at the same mode, you can realize it by sending some
control data together.
The data makes meaning with all bits, so you cannot stop the sending until all data transfer is over. But LA73026AV
adopt auto-increment, for example you can stop to transfer STOP condition after group 2 data . If you want to stop
transfer action, please transfer the STOP condition without fail.
*3
There are 3 control groups.
*4
This 8th bit called as R/W bit, and this bit shows the data transmission direction. [0] means send mode (accept mode
with SW IC) and [1] means accept mode (send mode with SW IC) fundamentally.

Specifications of any and all SANYO Semiconductor products described or contained herein stipulate the
performance, characteristics, and functions of the described products in the independent state, and are
not guarantees of the performance, characteristics, and functions of the described products as mounted
in the customer's products or equipment. To verify symptoms and states that cannot be evaluated in an
independent device, the customer should always evaluate and test devices mounted in the customer's
products or equipment.
SANYO Semiconductor Co., Ltd. strives to supply high-quality high-reliability products. However, any
and all semiconductor products fail with some probability. It is possible that these probabilistic failures
could give rise to accidents or events that could endanger human lives, that could give rise to smoke or
fire, or that could cause damage to other property. When designing equipment, adopt safety measures
so that these kinds of accidents or events cannot occur. Such measures include but are not limited to
protective circuits and error prevention circuits for safe design, redundant design, and structural design.
In the event that any or all SANYO Semiconductor products (including technical data,services) described
or contained herein are controlled under any of applicable local export control laws and regulations, such
products must not be exported without obtaining the export license from the authorities concerned in
accordance with the above law.
No part of this publication may be reproduced or transmitted in any form or by any means, electronic or
mechanical, including photocopying and recording, or any information storage or retrieval system, or
otherwise, without the prior written permission of SANYO Semiconductor Co., Ltd.
Any and all information described or contained herein are subject to change without notice due to
product/technology improvement, etc. When designing equipment, refer to the "Delivery Specification"
for the SANYO Semiconductor product that you intend to use.
Information (including circuit diagrams and circuit parameters) herein is for example only; it is not
guaranteed for volume production. SANYO Semiconductor believes information herein is accurate and
reliable, but no guarantees are made or implied regarding its use or any infringements of intellectual
