Looking for a processor which has following capabilities.

Hello Community,

I want to design a device with integrated ONU/ONT (optical network unit/terminal) and  (wifi + ethernet) router.

The requirements of the device are as follows...

1. Must have an optical fiber interface
2. Must have input & output ethernet (host-client) interface.
3. Data rate support up to 1/10 Gbps.
4. Must have an interface with both 2.4 & 5GHz wifi modules.
5. External flash memory interface.

The block diagram of the device is as follows...

Will you please help me to find the micro-controller/processor that is suitable for my application use case?

Regards,
Shiv Patil.
