Hello everyone,
i wanted to try and interface my Arduino MEGA with external memory. I have found a cheap one to play with. The brand of the memory chip is "Microchip 25LC010A". Because i haven't touched this kind of "area" ever...my question is do i interface with the memory chip by just using the Arduino's SPI library or with any other way? Any other memory chips that you can recommend?
Best regards and thank you in advance.
The chip you're referring to is an EEPROM with SPI interface (the term "memory" is a bit ambiguous). You can access it via the SPI library. With a bit of luck you may get this library also to work with your type (or write your own).
In the Arduino tutorial about the topic they use an Atmel chip.
Do you know that the MEGA already has 4kB of EEPROM (which is 32 times the capacity of the chip you're using)? You can use it by the EEPROM library.
Hi @pylon,
thank you so much for your quick reply! I know that the Arduino MEGA has much more memory than the EEPROM chip i posted the question about but i just wanted to experiment a bit with EEPROM and this chip is just a cheap one that i can use and play with! 
Best regards.
