I think it is possible to connect a SDA 2546-5 4kb EEPROM () via I2C to an Arduino,
but what changes from the guideline in http://www.arduino.cc/playground/Code/I2CEEPROM?
I connected the device exactly as indicated above, but I did not managed to get it work via the eeprom.pde.
Thanks in advance, I'm a newbie.  :smiley-red:

Do you have everything connected?
- GND SDA SCL, 5V

Please post the link to the datasheet, - specs should fit code !

Datasheet can be found here: http://www.alldatasheet.com/datasheet-pdf/pdf/168172/SIEMENS/SDA2546-5.html
I connected pins 1-4 to GND, 8 to 5V and SCL/SDA to arduino i2c pin 4 and 5 s as indicated in the tutorial.
Thanks for the quick reply!  XD

Page 4 of the datasheet, you need to connect the Chip Select pin 2 to +5V to select it .... ;)

I fixed the problem, but no reply from the eeprom.. What about device address? Is 0x50 right?
Sorry for wasting your time with such trivial issues...
Thanks again.
