graphic processing, the LCD controls, and backlights etc.
IC3302 RH-iXC773WJQZQ Main CPU This IC is Video Processor <FmSdata>[amp ] 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.
IC2002 RH-iXC786WJQZQ
for service
(RH-iXC786WJN5Q)
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-iXC790WJQZQ DDR This IC is 512Mb DDR2 SDRAM.
This IC operates as a memory of IC3302 (Video Processor). ***
IC4404 VHiAOZ1320C-1Y SMART LOAD SW The AOZ1320 is a P-channel high-side load switch with controlled slew rate.
AOZ1320-04 have a slew rate of 1ms.
IC3301 VHiBD6538G+-1Y USB high side SW BD6538G is single channel high side powers switch with low ON resistance Nch
power MOSFET.
Rich safety functions such as over current detection, Thermal shutdown (TSD),
under voltage lock out (UVLO) and soft start function which are required for the
power supply port protection are integrated into 1chip.
IC501 VHiBR24C21F-1Y
for service
(RH-iXC697WJQZS)
1K E2PROM This IC is a 1Kbit-2-wire (I2C bus type) serial EEPROM that can be programmed
electrically. The EEPROM chip stores the EDID data of PC input. This data is con-
trolled through I2C signals.
IC2601/
9611
VHiHC2G66DP-1Y Bilateral Switch This IC is provides a dual analog switch. Each switch has two pins for input or out-
put and an active HIGH enable input.
IC9604/
9606
VHiLV58072M-1Y 1CH-SW-REG LV58072M is 3A 1ch step down switching regulator.
In this model, it generate D1.1V.
IC9605/
9608
VHiLV5893M+-1Y 1CH-SW-REG LV5893M is 1.8A 1ch step down switching regulator.
In this model, it generate BU3.3V.
IC8455 VHiM24C64WN-1Y I2C bus type
-64K E2PROM
The BR24S64W is a 64Kbit-2-wire (I2C bus type) serial EEPROM that can be pro-
grammed 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 provides the electrical inter-
face between an asynchronous communication controller and the serial-port con-
nector. The charge pump and four small external capacitors allow operation from a
single 3V to 5.5V supply.
IC9603 VHiMM3141YN-1Y 1CH-SW-REG
Reg 1.25V
The MM314 is CMOS general-purpose single-output voltage regulators with an on/
off control input, featuring low dropout voltage and low quiescent bias current. The
output current is possible up to 150mA or less. In this model, it generate CPU2.5V.
IC4405 VHiMT8295AE-1Q CI controller This is a control IC for PCMCIA cards. This controls information on IC cards
inserted into the PCMCIA card slot (SC4401) or information on software version
upgrade cards saved on flash memories to transfer the data to CPUs and memo-
ries.
IC1107 VHiPQ1LA505-1Y Reg 5.0V The PQ1LA505 is CMOS general-purpose single-output voltage regulators with an
on/off control input, featuring low dropout voltage and low quiescent bias current.
The output current is possible up to 500mA or less. In this model, it generate DC-
POW.
IC9610 VHiPQ1LAX95-1Y Reg 9V The PQ1LAX95 is CMOS general-purpose single-output voltage regulators with an
on/off control input, featuring low dropout voltage and low quiescent bias current.
The output current is possible up to 500mA or less. In this model, it generate S+9V.
IC2004 VHiS24CS08J-1Y EEPROM The 24CS08 is a 8Kbit-2-wire (I2C bus type) serial EEPROM that can be pro-
grammed 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.
IC2001 VHiS80927NM-1Y Reset This IC is a highly precision voltage detector (2.7V) with built-in delay circuit.
