MCB517AC Evaluation Board User’s Guide 11
Chapter 3. Hardware
The MCB517AC is designed to be a very flexible evaluation board that you can
use to become familiar with an 80C517A microcontroller and an 80C91 full
CAN controller. We have also tried to provide a board that can be expanded to
support your own hardware prototypes.
This chapter describes logical sections of the MCB517AC and also provides a
circuit description. The descriptions here will help you understand how the
MCB517AC board works and how you can easily interface to the various I/O
devices available.
The following block diagram shows the various memory, I/O, configuration, and
power systems that compose the board.
