Hi Group!
I am new to embedded systems. I have an application to develop. In that i need to maintain a data storage, uneffected by power loss. So it means i need to use an external storage device with my Microcontroller? I am using Atmel-89C52. I have a few queries:
1)What should be my choice for data storage device...i think EEPROM? 2)If yes, then the Atmel AT24CXX or Xicor X4283 etc could be possible choices? These are serial EEPROMs with 2/3 wire interfaces. 4)If these are not good choices, can anyone suggest some other devices that can be integrated with 89C52 and can hold upto 64K bits data?4)I also need to keep the time record in my application. So i need a Real time clock IC? what would be my best choice in terms of best integration with 89C52 via minimum interface wires?
Thanks Rider
