  LC-32GA8/LC-32BV8
  LC-37GA8/LC-37BV8
· 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.
· 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 configuration information for optimal use of a display (EDID data).
