How to use 128 Bit I2C™ Bus Serial EEPROM (24AA00/24LC00/24C0)..??

[koolguy]

Hi,

i have got this 24AA00/24LC00/24C0 memory ic, the data sheet for it shows it works serially.
can i use it for saving data??

 

[Nigel Goodwin]

Yes, it's a standard (very small) I2C EEPROM, you just need to write the I2C software to feed it.

but,How..??

Google for it - you haven't even mentioned what processor you're wanting to use - if it's a PIC my tutorials cover it.

Can i use it without using uP??

Can i use it without using uP??

Yes, it should be possible if you have enough hard wired logic,
or
you simply use it for soldering practice if you have a suitable circuit board.

No, not really - but why would you want to?, I suspect you don't understand what it actually is?.

can you me block diagram how to read & write. as it ask for serial bits order.

 

[koolguy]

it's a PIC my tutorials cover it.

Please give the link of it.

 

[Nigel Goodwin]

Please give the link of it.

It's at the bottom of everyone of my posts, are you using a PIC then?.

 

[koolguy]

are you using a PIC then?.

I don't have any PIC!!

 

[Nigel Goodwin]

So what processor are you using, and what are you wanting to do with the EEPROM anyway.

 

[koolguy]

I want to use it, for saving data.. any type, for my circuits.

Then you don't need to know how to use it until you have an actual application - but as we've said, it's a puny size, and most PIC's have as much (or more) internal data EEPROM storage. The common application for them was in storing tuning information in fairly old TV's (anything remotely 'modern' uses a MUCH larger EEPROM to do so).

As in tv sets or CD players,etc.. when we switch off the devices the channel & voice level remain the same how does it happen?? they also uses these EEPROM.

The processor writes the values into EEPROM, and when you turn it back on, it reads them back out - it's quite simple.

 

[koolguy]

That mean every playeres or tv sets have internal uP & EEPROM.

Of course, why would you imagine they don't? - although it's usually micro-controller, not micro-processor.

 

[koolguy]

OK, i was thinning they use ic's counter which automatically store the data.

If you want a portable radio that costs hundreds of pounds, is huge, and requires a strong man to carry it, then you 'could' do it in hardware - but it would be a completely pointless exercise.
