Serial EEPROM programmer circuit
This Serial EEPROM programmer is very simple and require few external electronic parts .
The Serial EEPROM programmer connects to the PC parallel port and is controlled by driver software running on the PC. The programmer requires a 9-to-12V DC supply at 50mA.
This Serial EEPROM programmer supports the following EEPROM types :
2401, 2402, 2404, 2408, 2416 , 2432, 2464, 24128, 24256 , 9346, 9356, 9366, 9376, 9386 .
These small 8 pin devices offer non-volatile data storage and require minimal I/O lines to connect to them.
In the schematic circuit below is presented another programmer that supports the following types 24CXX, 24LCXX, 93CXX and 93LCXX of EEPROMs and needs to be powered from a 5 volt DC power supply .
If you want to build just a 24LCxx,24Cxx programmer you can use the following circuit diagram which connects the device to PC using Serial Port .
This circuit is powered directly from the computer’s serial port and don’t require any other power supply .

please help me,if you have
You can use the last circuit
Hi So, what are the component
C1 - 47uF; C2 - 0.1uF;
Wich software I can use to
I think that will work with
in last diagram ,if we use
In the last circuit, EEPROM
Can we write with this
