That 1 MB Flash is large enough to hold a full TCP/IP stack, a CANopen or EtherCAT slave stack, and application code without splitting firmware across external memory. The 136K x 8 RAM supports multiple data buffers for Ethernet frames and USB transactions. The EBI/EMI port allows glueless connection to external memory or parallel peripherals.
