This IC is 2048Mbit NAND flash memory.
This IC stores the software data that processes the system of TV such as 
the graphic processing, the LCD controls, and backlights etc. 
IC3303
RH-iXD220WJQZQ
Digital AV decode
Main CPU
This IC is Video Processor & MAIN CPU.
In this IC, the decode processing and the video signal processing are done.
Moreover, OSD is generated here and added to a picture signal.
IC2001
RH-iXD241WJQZQ for 
service
(RH-iXD241WJNWQ)
UCOM
The monitor microprocessor is intended to communicate with the main CPU 
and to operate the system.
It also controls power of the entire system.
IC3501/3502
RH-iXD242WJQZQ
DDR
This IC is 2GB DDR3 SDRAM.
This IC operates as a memory of IC3303 (Digital AV decode & Main CPU). 
IC8455
VHiBR24S64F-1Y
64K bit E2PROM
The BR24S64 is a 64Kbit-2-wire (I2C bus type) serial EEPROM that can be 
programmed electrically.
This IC stores the menu data and the adjustment value data of adjustment 
process mode etc.
The data is given out by commands from the main microprocessor.
IC506
VHiM3221EiP-1Y
RS232C-DRIVER
The MAX3221E is a single driver, single receiver RS-232 solution operating 
from a single Vcc supply. The RS-232 pins provide IEC G1000-4-2 ESD 
Protection. The device meets the requirements of TIA/EIA-232-F and pro-
vides the electrical interface between an asynchronous communication 
controller and the serial-port connector. The charge pump and four small 
external capacitors allow operation from a single 3V to 5.5V supply. 
IC4402

(USB) Specification Revision 2.0 and works up to 480 Mbps. USB 2.0 com-
pliant transceivers are integrated for upstream and all downstream ports.
The IC4 works backward compatible either when any one of the down-
stream ports is connected to a USB 1.1 compliant device, or when the 
upstream port is connected to a USB 1.1 compliant host.
IC2703
VHiYDA164BZ-1Y
Audio-AMP
This IC is digital audio power amplifier with digital audio interface.
The power-supply voltage is corresponded to A.5V~18V and the maximum 
output is 20Wx2ch. 
IC1105
(LC-60/
70LE740E, 
RU,743E only)
RH-iXC563WJQZY
LNB supply and
control
It is IC for amplifying the feeble electric wave sent from satellite broadcast-
ing on the level which can treat a decoder, and changing and processing 
signal.
