How to write data to M24C04 EEPROM?

[sreeprathap]

Hi All,

How can I load data to M24C04 EEPROM?
I am very new to this. I don't have any basic idea about writing data to EEPROM.
Can we write the data using a PC? Do we have to use special hardware for this operation?

It's possible via the parallel port ..
Here is an example with bigger EEProm, but the same principle applies to the 24C04:

Also, see:

MemPlus 1.2 works with a lot of EEProms ..

Thank you for your valuable information.

I would like to is there any dedicated hardware (equipment) available in market which is used for writing data to EEPROM. This device should also be programmable through PC. That is by sending the commands from PC (maybe using serial communcation) we should be able to download data to EEPROM using this device.

If you know any vendor or distributor related to this product please let me know...

Thanks in advance...

Free software with minimum hardware, maybe this will help you read and write to EEPROM.
