I'm developing a Holter system for my microcontrollers course for university.
We're using the 8051 (more specifically, AT89S52) microcontroller and we need to store a large amount of data (64MB approx) product of the recording the holter performs (that's what it does, basically a kind of a recorder).
The thing is that i've looked up in many webs and i still can't find an adequate memory for doing this and the way to interface to that memory (though i suppose that once i get the memory i'll deal with that issue using the datasheet).
Every suggestion will be very welcome. Peace!
I'd give up on the '51 and usae a chip with a dynamic memory interface.
if you have enough time between the stores an option is to use a flash card (disk formatted).
