EZ80 EVALUATION BOARD

The eZ80 Evaluation Board comes packaged with everything you need to start developing your application, including:

• ZPAK emulator
• serial cable for COM1 and crossover UTP networking cable
• power supplies for the evaluation board and ZPAK emulator
• three CDs containing the Zilog development system, an eZ80 C compiler, and IPWorks TCP/IP networking software
• manuals for the evaluation board and ZPAK emulator

Photo 1 shows a close up view of the evaluation board. The eZ80 CPU (operating at 40 MHz) is just one chip of many, including 1 MB of flash memory, 1 MB of RAM, 10BaseT Ethernet, and dual RS-232 channels. Two 60-pin expansion headers provide for external memory and general-purpose I/O interfacing.
