This is a more detailed block diagram of the vending application. The value of the eZ80Acclaim!™ devices, are that they provide plenty of power to handle the various interfaces but still maintain an 8-bit design footprint for low-cost implementation. Before the eZ80®, the 8-bit MCUs inside vending machines were very simple, not even being able to handle the extra requirement of network connectivity. Many engineers initially wanted to move to 32-bit processors to do the job; however, the cost was too high to implement. With the eZ80®, you get the best of both worlds—network connectivity and low-cost.
