In our second class, we will investigate an innovative example circuit for interfacing with the myriad industrial Ethernet standards: the Renesas RZ/N1D chip and its development board set. The RZ/N1D is a multiprocessor system-on-a-chip that provides dual ARM Cortex-A7 cores for application processing and system control along with a Cortex M3 chip as a dedicated control processor for up to five high-speed Ethernet ports. We will look at depth at the various other ports and features of the hardware provided in this 400 pin BGA IC.
