Description
The STEVAL-IFW002V1 is an FPGA extension of the STEVAL-IFW001V1. This extension board 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 the STR912FA microcontroller, such as timers, communication I/Fs. Communication between the STR912FA demonstration board and the extension can be achieved through a medium independent interface (MII), external memory interface (EMI), SPI™, GPIOs or by other methods. RT Ethernet evaluation requires both the STEVAL-IFW0001V1 demonstration 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.
