Dear all,
I am new in this forum.
I looked carefully all around but I cannot find this information:
the GPMC max speed is → 16 bit X 100 MHz = 1.6 Gbit/s
I would like to know that information for the SPI case (probably it is written somewhere in capital letters but I missed it…).
Could you please help me?
Thanks a lot.
Hi Alberto,
not entirely sure what your question is, but the SPI transmission rates can be anywhere from a couple of kilohertz to a couple of megahertz. It would pay to look at the datasheets or Technical Reference Manuals for the chips you are looking to interface. For example an Arduino can accept SPI speeds up to Fosc/2 or 8MHz.
Other, single chip, devices are sometimes lower than that around 1MHz.
I doubt you will find an SPI operating at GHz speeds.
