Hi,
I would like to know how I can identify a SPI EEPROM. I tried this one "93C06" however, I couldn't find anything related to 3 wire or SPI in the official datasheet.
What are your approaches to identify this type of circuits ?
Last question:
Can anyone send me a datasheet link for this circuit "Atmel 436 74c04"
Thanks.
Did you try looking for parts at Digikey?
These are thru hole components as one example with SPI interface
Not enough info provided on the Atmel part.
You could try Atmel customer service, see if they help identify that part.
Give them as much info as you can - part markings, package type, 3 of pins.

The datasheet says "microwire bus".

Google found that ^ in about 10 seconds.
It looks as though it not SPI, although it is serial. Page 5 talks about the interface and it appears to be called 'Microwire'.
It appears to be similar to SPI so maybe you can use the same library but in a non traditional way, if not there is likely an Arduino Micro wire library somewhere out there someone has made.
