· IC2702 & IC2705: VIDEO INPUT SELECTOR.
Part number: MM1507XN
Sharp code: VHIMM1507XN-1Y
This IC extends the series of ICs for video/audio signal switching, with a
2-input 1-output single video switch with 75Ω driver and input clamp.
· IC3001 : NVM 64Kb-E2PROM
Part number: BR24L64F
Sharp code: VHIBR24L64F-1Y
The BR24L64F is a 2-wire (I2C bus type) serial EEPROM that is electrically programmable. This IC stores the control
data of system contents (last memory, for example) for the main microprocessor's AV PWB and main PWB. The data
is given out by commands from the main microprocessor.
· IC3003 : PIC MICROCONTROLLER
Part number: PIC16F913
Sharp code: RH-IXB664WJZZY
28 Pin Flash-Based, 8 bit CMOS Microcontrollers with LCD Driver and nanoWatt Technology.
This IC is controlled via I2C and works how expander of ports. This IC has led control and include A/D converter.
· IC3005: RESET IC FOR VCTP (IC3002)
Part number: BU4215G
Sharp code: VHIBU4215G+-1Y
Low voltage detector IC with adjustable output delay. Standard detection
voltage = 1.5V
· IC2301 : RS-232 TRANSMITTERS/RECEIVERS
Part number: ISL83220
Sharp code: VHIISL83220-1Y
The ISL83220E is a 3.0V to 5.5V powered RS-232 transmitter/receiver,+/-15kV ESD protected, minimum data rate
250 kpbs.
· IC2303 : NVM OF PC MODE (EDID)
Part number: BR24C21F
Sharp code: VHIBR24C21F-1Y
This IC is a 2-wire (I2C bus type) serial EEPROM this is electrically programmable. This EEPROM chip stores the
data structure used to carry confi guration information for optimal use of a display (EDID data).
· IC1701: POWER RESET OF +BU1.8V
Part number: BU4239G
Sharp code: VHIBU4239G+-1Y
Low voltage detector IC with adjustable output delay. Standard Detection Voltage = 3.9V
· IC1702: BU+3.3V (VOLTAGE INPUT: BU+5V)
