· · 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).
