Hi Seemanta, I would suggest you the I2C serial memories, just because is the only I know and only I already worked with although I'm not very experienced with they too.
You can use: AT24C32, AT24C64, AT24C128, AT24C256, AT24C512 For: 4KB, 8KB, 16KB, 32KB and 64KB respectively Dont know about other protocols, but I2C gives you ability to use more than one device in same bus, so you can use more than one IC, mixed or not. For exactly how much ICs you can use you will need to see the IC datasheet, because many ICs has a limited address selection. You can get information on I2C on Wikipedia, here: http://en.wikipedia.org/wiki/I%C2%B2C Also this link has a working I2C procedure for this type of memory: http://www.microcontrolador.com.br/forum/vie...ontrolador I hope this helps you. (PS:Please correct me if I'm wrong in something) Thanks a lot for your detailed reply, Chico! |
