This document provides an overview of micro-controller systems and their features. It discusses the evolution from large computers to single-chip embedded controllers. Micro-controllers have limited components and are programmed with high-level languages. They contain various memory types including RAM, ROM, EEPROM and flash. Micro-controllers also feature things like timers, interrupts, analog to digital converters and serial I/O. They can operate with different architectures like Von Neumann or Harvard and use number systems like binary, decimal and hexadecimal. Recommended resources are provided to learn more.

- 1. Micro-controller Course Mohamed Fadel Barakat Introduction Micro-computer Systems
- 2. Agenda Micro-computer Systems. Micro-controller Systems. Micro-controller Features. Micro-controller Architectures. Number Systems.
- 3. Micro-computer Systems • Large computers to a single-chip embedded controller.
- 4. Micro-controller Systems • Limited components. • Programmed with High-level languages.
- 8. Micro-controller Systems’ Memories • RAM. • ROM. • PROM (OTP). • EPROM (ultra-violet). • EEPROM (electrical). • Flash EEPROM.
- 9. Micro-controller Features • Supply Voltage (Regulator). • The Clock Speed. • Timers (Counters || Comparator). • Watchdog (Handler Timer). • Reset Input. • Interrupts.
- 10. Interrupt

- 13. Micro-controller Features • Real-time Clock (Date & Time). • Sleep Mode (Wake Up by Reset). • Power-on Reset. • Low-Power Operation. • Current Sink/Source Capability (25mA max). • (USB | Motor Control | CAN | Ethernet | ZigBee)Interface.
- 14. Micro-controller Architectures Von Neumann architecture Harvard architecture
- 15. Micro-controller Architectures • RISC vs. CISC • Refers to the instruction set of a microcontroller. • CISC 8-bit wide both data and instruction (e.g. Intel). • RISC 8-bit wide data and 16-bit wide instruction. • RISC Instructions are fetched and executed in one cycle (e.g. Motorola).
- 16. Number Systems • Decimal (base 10). • Binary (base 2). • Octal (base 8). • Hexadecimal (base 16). • We already know how to convert from one system to another
- 17. Reference • Best Recommended Book “Advanced PIC Microcontroller Projects in C” for Dogan Ibrahim. • PIC18F4550 datasheet.
