Hi
Is there anyone who knows if Nordic has SoC`s with Camera Interface ,the Camera is CMOS parallel data rate 20 - 27MHz
Thanks

Our peripherals runs on a 16MHz clock, and our CPU's at 64MHz. So that's not really feasible.
Maybe you can bit-bang it with the 128MHz CPU of the new nRF5340, but it depends on how many I/O lines you need.
Hi
What is the peripherals rate on nRF5340?
Thanks
Still 16MHz, but the GPIO peripheral is not synched to the 16MHz clock (GPIOTE is), so the CPU might be able to drive them faster than 16MHz.
A 27MHz parallel interface is a bit tricky for ULP cortex-m platforms.

how many I/O lines does this interface use?
8 I/O
HSYNC
VSYNC
PCLK
Hmm,
At 27MHz you'll have 128/27 = 4 clock cycles to find the next state of the pins and update the GPIO register. That's not feasible.
You'll probably need a minimum of 20 clock cycles of a fully optimized code to bit-bang such an interface, so that's at least a ~20*27MHz = ~540MHz CPU. And that's given that the internal memory bus and GPIO peripheral are fast enough.
You're probably better off looking for a dedicated interface IC.
