Overview

LC786830 Demo Board Kit is a demonstration and development
platform based on LC786830. The kit also contains a Downloader
Board so that you can easily update programs from your PC. The kit is
designed to showcase multimedia audio playback including
Bluetooth

This manual provides detailed information about the use and the
configuration of the LC786830 Demo Board Kit to help you evaluate
the performance and capabilities of LC786830 in developing
application software for it.

LC786830 Demo Board Kit comprises Main Board, LCD Board and
Downloader Board. The Main Board features miscellaneous
components to show the performance of LC786830. The LCD Board
has buttons as well as a LCD module for user interface.

Power Supply

The enable pins of three LDOs on the Main Board are
connected to pins of LC786830 via jumpers. Thus, place
shunt jumpers on pins 2 and 3 of JP1, JP2 and JP3 before
powering the Main Board except when each state can be set
by GPs. Refer to the following table and figure. After that,
connect the plug of a 12 V power supply to the DC jack
(CN501, center positive, up to 4 A).

The Flash Writer Application can program the flash

Downloader Board. The Flash Write Application is
available from the onsemi.com website.

Applications

Bluetooth module NF2210EZ is embedded on the Main
Board with printed antenna so that it is easy to establish a
Bluetooth connection with a phone or other device. An
electret condenser microphone is also embedded on the
Board for hands−free communication. It has a gain of 40 dB.
If you do not achieve that in your environment, please
replace resistors, R662 and R665 to adjust the gain.
Although the built−in DAC of the LC786830 supports up to
96 kHz sampling rates, external DACs which can accept
192 kHz sampling rates also are featured on the Board so
that 192 kHz sampling rates playback is acceptable. When
the output level of GP04_4 is low, built−in DAC outputs are
connected with RCA jack. When the output level of GP04_4
is high, external DAC outputs are connected with RCA jack.
Refer to the schematic of the Main Board. The 3.5 mm phone
jack is connected to a differential input on the LC786830 to
accept an analog input. The Main Board also has an
EEPROM for backup applications such as storing volume
settings. The SD Card socket is embedded on the solder side
as well. The Main Board can mount PSRAM but the
PSRAM needs to use same ports of LC786830 as the SD
Card control. Therefore, when PSRAM is available, the SD
Card solution is not available. In addition to that, there are
a piezo speaker and an IR receiver on the Main Board for
applications. Furthermore, the Main Board can be connected
with ON Semiconductor’s CD playback Board so that it is
easy to support a CD solution. A dedicated IIC interface is
available for MFi, via a CN102A terminal on the Main
Board.

For details of each component on the Boards, refer to its
datasheet.

Debugging

A Serial Wire Debug interface is available for debugging.
CN103 (JTAG 20−pin connector) on the Main Board is its
adaptor connector.

EVBUM2769/D

The microcontroller on the Board supports programing of
the flash on the Main Board from your PC. Place shunt
jumpers on pins 2 and 3 of JP101 and turn all switches of
DSW1 off. Reset switch, TSW1 controls the reset status of
the Microcontroller. The reset is active low. With the
Downloader Board connected to the Main Board, TSW1
must be turned to L (low) when debugging.

ON Semiconductor and the ON Semiconductor logo are trademarks of Semiconductor Components Industries, LLC dba ON Semiconductor or its subsidiaries in the United States and/or
other countries. ON Semiconductor owns the rights to a number of patents, trademarks, copyrights, trade secrets, and other intellectual property. A listing of ON Semiconductor’s
product/patent coverage may be accessed at www.onsemi.com/site/pdf/Patent−Marking.pdf
subject to all applicable copyright laws and is not for resale in any manner.

The evaluation board/kit (research and development board/kit) (hereinafter the “board”) is not a finished product and is as such not available for sale to consumers. The board is only intended
for research, development, demonstration and evaluation purposes and should as such only be used in laboratory/development areas by persons with an engineering/technical training
and familiar with the risks associated with handling electrical/mechanical components, systems and subsystems. This person assumes full responsibility/liability for proper and safe handling.
Any other use, resale or redistribution for any other purpose is strictly prohibited.

The board is delivered “AS IS” and without warranty of any kind including, but not limited to, that the board is production−worthy, that the functions contained in the board will meet your
requirements, or that the operation of the board will be uninterrupted or error free. ON Semiconductor expressly disclaims all warranties, express, implied or otherwise, including without
limitation, warranties of fitness for a particular purpose and non−infringement of intellectual property rights.

ON Semiconductor reserves the right to make changes without further notice to any board.

You are responsible for determining whether the board will be suitable for your intended use or application or will achieve your intended results. Prior to using or distributing any systems
that have been evaluated, designed or tested using the board, you agree to test and validate your design to confirm the functionality for your application. Any technical, applications or design
information or advice, quality characterization, reliability data or other services provided by ON Semiconductor shall not constitute any representation or warranty by ON Semiconductor,
and no additional obligations or liabilities shall arise from ON Semiconductor having provided such information or services.

The boards are not designed, intended, or authorized for use in life support systems, or any FDA Class 3 medical devices or medical devices with a similar or equivalent classification in
a foreign jurisdiction, or any devices intended for implantation in the human body. Should you purchase or use the board for any such unintended or unauthorized application, you shall
indemnify and hold ON Semiconductor and its officers, employees, subsidiaries, affiliates, and distributors harmless against all claims, costs, damages, and expenses, and reasonable
attorney fees arising out of, directly or indirectly, any claim of personal injury or death associated with such unintended or unauthorized use, even if such claim alleges that ON Semiconductor
was negligent regarding the design or manufacture of the board.

This evaluation board/kit does not fall within the scope of the European Union directives regarding electromagnetic compatibility, restricted substances (RoHS), recycling (WEEE), FCC,
CE or UL, and may not meet the technical requirements of these or other related directives.

FCC WARNING – This evaluation board/kit is intended for use for engineering development, demonstration, or evaluation purposes only and is not considered by ON Semiconductor to
be a finished end product fit for general consumer use. It may generate, use, or radiate radio frequency energy and has not been tested for compliance with the limits of computing devices
pursuant to part 15 of FCC rules, which are designed to provide reasonable protection against radio frequency interference. Operation of this equipment may cause interference with radio
communications, in which case the user shall be responsible, at its expense, to take whatever measures may be required to correct this interference.

ON Semiconductor does not convey any license under its patent rights nor the rights of others.

LIMITATIONS OF LIABILITY: ON Semiconductor shall not be liable for any special, consequential, incidental, indirect or punitive damages, including, but not limited to the costs of
requalification, delay, loss of profits or goodwill, arising out of or in connection with the board, even if ON Semiconductor is advised of the possibility of such damages. In no event shall
ON Semiconductor’s aggregate liability from any obligation arising out of or in connection with the board, under any theory of liability, exceed the purchase price paid for the board, if any.
