Is arduino suitable for high frequency application? Can I use the arduino for an application with a frequency of 4 MHz?

I need to create a clk with this frequency and send and receive data on the rising and falling edges. and it is not a normal SPI interface I have my own conditions so I need to do it manually.

If it is not suitable, is it technically possible?
Most Arduinos are based on AVR chips clocked at 16&nbsp;MHz. On those,
you can generate a 4&nbsp;MHz clock using hardware timers. Bit-banging
data at this speed would be difficult though. It may be possible,
using unrolled loops and hand-crafted assembly... or not, depending on
the specifics of your application. Even if possible, it would be a nice
challenge for an assembly programmer.

The Arduino Due is based on an ARM chip clocked at 84&nbsp;MHz. This
gives you more leeway to bit-bang at 4&nbsp;MHz. But even on the Due you
would certainly need hand-crafted assembly.
