• STEVAL-IFW0002V1, FPGA Extension Board of the STEVAL-IFW0001V1 STR912FA dual Ethernet PHY carry board. This extension was designed to handle a real-time (RT) Ethernet IP (e.g. RT HUB for Powerlink, IEEE1588, EtherCAT IP, etc). It can also be used for evaluation of other IPs connected to STR912FA microcontroller, such as timers, communication I/Fs, and others. Communication between the STR912FA evaluation board and the extension can be done through a medium independent interface (MII), external memory interface (EMI), SPI, GPIOs or other methods. RT Ethernet evaluation requires both the STEVAL-IFW0001V1 evaluation board and STEVAL-IFW0002V1 extension board. Typically, the STR912FA microcontroller communicates with the on-extension real-time Ethernet logic which, in turn, communicates with the two on-board Ethernet transceivers and the microcontroller
