Good morning guys, I'm new to this and I have the task of upgrading to an industrial automation system (PLC type) in real time based on an ARM CORTEX M0 (LPC1224FBD64 from NXP).
The system uses 2 RS485 communication channels but it will also be necessary to implement an IRED communication system. The new hardware will have about 55 ports. I will have to decide if we move to M0 + but we also don't want to use chips with more than 64 pins.
Are there any suggestions for the chip to use? Is it worth switching to M0 +?
I suggest you discuss this with your Distributor and/or NXP FAE(s) - then you can go into specific details with them.
