COURSE DESCRIPTION: A foundation course designed to prepare the student with the key concepts of microprocessor architecture, interfacing, programming and design. The basic skills required to use the microprocessor as a tool in solution of electronic design problems will be taught and practiced. THE INSTRUCTOR'S PHILOSOPHY: I am more than happy to help students at any time in any way that I can. However, I believe that there is a responsibility on the part of the students to get the most that they can from any course. I would recommend that each student do the following in order to gain the most from this course: read each assignment before coming to class, do all homework assignments, never miss a class or a lab, and take detailed class notes. I hope that students will rate this course by comparing what they know now with what they have learned at the end of the course. If students will apply themselves I think they will be very pleased with what they will gain from taking EET 2790. Please contact me if you are having any difficulties as soon as possible so that I can help you before a problem gets too big. OFFICE HOURS: My office is located in the Technology Building in room 131, my phone number is 586-7981, and my email is ward@suu.edu. I am usually in my office from 8:00 am to 9:00 am daily. However, there may be times when I am called to a meeting or am out of my office for other reasons. If you need to meet with me at a particular time please make an appointment and see that I write it down. REQUIRED MATERIALS: Textbooks: The Z80 Microprocessor Architecture, Interfacing, Programming and Design, third edition by Ramesh Gaonkar. Easy PIC’n A Beginner’s Guide to Using PIC 16/17 Microcontrollers, By David Benson STUDENT GRADING: Exams and unannounced quizzes 50% A = 90 to 100% Homework 10% B = 80 to 89% Lab assignments 35% C = 70 to 79% Attendance 5% D = 60 to 69% F = below 60% If a student does not contact the instructor prior to missing a quiz or exam that quiz or exam cannot be made up.

HOMEWORK: All late assignments will be penalized 20% per day. All homework will be due at the beginning of the class period, class and lab time cannot be used to do homework assignments. LAB ASSIGNMENTS: Due dates of the lab assignments will be given as the class progresses. Lab assignments will be graded on the following: correctness and completeness of your answers, the write-up of your conclusions, spelling, neatness and grammar. A.D.A.

4

recommendations, for at least 10 different Z80 instructions. f). Explain the difference between machine language and assembly language.

IV. Generating Status Information

a). Explain the differences between the internal and external buses in a Z80 based microcomputer system. b). List the sources and destinations of information that appears on the external data bus. c). Explain the differences between a state, clock cycle, instruction cycle, and machine cycle.

V. Input/Output (I/O) Devices

a). Latch the output from the accumulator of a Z80 based microcomputer with the aid of any one of 6 different integrated circuits: 7475, 74100, 74145, 75193, 74198, and the 74124. b). Input TTL data into the accumulator with the aid of either a 8095 or 8212 buffer IC’s. c). Explain what a data logger is. d). Calculate the timing delays required to data log digital information appearing at different rates.
