The DSTINIm400 is a fully assembled and tested circuit board that evaluates the DS80C400 network microcontroller. In addition to the DS80C400, the DSTINIm400 includes a real-time clock, 1MB flash, 1MB static RAM, and support for an external Ethernet PHY for connecting to a wide variety of networks. The circuit board is designed as a module to be plugged into a 144-pin SODIMM connector. For evaluation, the DSTINIm400 can be inserted into the DSTINIs400 socket board. The combination of the two boards allows full evaluation of the features of the DS80C400 using an Ethernet network.
