Maximum write speed to external Miniflash cards via SPI

[Anonymous]

I would like to us the SD flash as a data logger function. Does anyone know the maximum speed for writing? Also are there any other things to consider? Such as: Do I need pause statements after a write? I saw an app note that was using 24Mhz divided by 2. I am not sure how stable the data is at this speed. I would like to use the PSoC 5.

       

Thanks

philip,

       

are you using spi for communication?

   

if so, then the maximum speed which you can use will be the maximum speed which spi will allow you to communicate with.

   

the spi clk speed will be 1/2 of the speed of the clock connected to the spi master component.
