Dear Andy

Well you got a point Andy, but the requirements of using the MCU board are requested by our customer and also my superior. I think they have better explaination to this since they are much-much more experience than me on technical side and business side.

As for me, the way I see of using the MCU board is to make it more robust and secure the algorithm of data encryption.


so is't my choice of using Cypress Chip CY7C68013 right?

Thanks
