IMPLEMENTATION STRATEGIES:

First introduce the simple model of microprocessor i.e. generalized block diagram of microprocessor. Then introduce the specific microprocessor i.e. 8085 microprocessor. Make the students familiar with the instruction set, programs, timing diagrams and particular operations.

Introduce various interfaces and typical applications related with the same. Develop awareness of microcontroller and its importance in the field of Electronics and latest technology.
