Dear all, I'd like to use AT89C51 for sampling. The samples are going to store in a external RAM. Is the sampling rate equals the oscillator attached? I heard that the max rate is less than 500ksps, isn't it? Thanks. Bill
half a question will not get you and answer. The AT89C51 does not have a A2D. So will you be using a serial or parrallel one? How many bits. ASM or C? or both?
I am going to use AD7825 which is 2Msps and 8 bit. I wonder if the uC could handle it even it has 12MHz oscillator and RAM attached. Moreover it has to calculate from the samples.

I do believe that the AT89C51 is a 12 clocker and since read port, movx, inc dptr is a tyotal of 6 cycles, tha maxx read yoy will get will be (12MHz /12) /6 if you need speed you need look at SILabs Erik
