I am working on a 4G/LTE router hardware design and currently at Microcontroller selection stage.
Design is going to have following interfaces:
5 Digital I/O's
5 Analog I/O's
2 RJ45 port – Ethernet Connectivity
2 RS232/RS 485 Port
2 USB Ports
1 HDMI Port
LTE/4G Cellular Connectivity/GSM Connectivity
Wireless Connectivity - Wifi/ LoRa / Sigfox / LowPan
I have 2 controllers in mind: Microchip ATSAMA5D36 & TI CC3220.
It would be great to have few suggestions on controller/processors which support above interfaces at minimum processing power possible.
With the above specifications, I would consider using some Cortex-A8, for example the Allwinner-A10 for which you could even find lot of development boards from different brands.
Sometimes, to make the right choice, you have to consider not only the hardware platform itself, but also the popularity of the core, which translates into more development kits available and possible further support. As for this NXP stuff I do not know, but have you tried to find out what development kits are based on it as well as the size of the user community on the manufacturer's forum or third-party partner kits ?
