1) The document discusses the differences between microprocessors and microcontrollers. 2) A microcontroller integrates a microprocessor, memory, and input/output ports onto a single chip to make it suitable for applications where cost, power and space are critical constraints. 3) In contrast, a microprocessor-based system has the CPU, memory, and I/O components separated, allowing for more flexibility but also greater expense, higher power consumption, and larger size.

3.  Embedded Systems
• Operations managed behind the scenes by a
microcontroller
 Microcontroller (MCU)
• An integrated electronic computing device that includes
three major components on a single chip
1. Microprocessor (MPU)
2. Memory
3. I/O (Input/Output) ports
Microcontrollers

4.  Support Devices
 Timers
 A/D converter
 Serial I/O
 Common communication lines
 System Bus
Microcontrollers

5. Block Diagram

6. Microprocessor (MPU)
 MPU (CPU)
 Read instructions
 Process binary data

7. Memory
 Storage Device
 Addresses
 Registers
Major Categories
 Read/Write Memory (R/W)
 Read-only-Memory (ROM)

8. Input/Output (I/O)
 Input Devices
 Switches and Keypads
 Provide binary information to the MPU
 Output devices
 LEDs and LCDs
 Receive binary information from the MPU

9. Microprocessor Architecture
 The MPU communicates with Memory and I/O using the System Bus
 Address bus
• Unidirectional
• Memory and I/O Addresses
 Data bus
• Bidirectional
• Transfers Binary Data and Instructions
 Control lines
• Read and Write timing signals

10. Microprocessor-Based System

11. Example Microprocessor System

12. • CPU is stand-alone, RAM, ROM,
I/O, timer are separate
• designer can decide on the amount of
ROM, RAM and I/O ports.
• expensive
• versatility
• general-purpose
• High processing power
• High power consumption
• Instruction sets focus on processing-
intensive operations
• Typically 32/64 – bit
• Typically deep pipeline (5-20 stages)
Microprocessor vs. Microcontroller
Microprocessor

13. •CPU, RAM, ROM, I/O and timer are all on a single chip
•fixed amount of on-chip ROM, RAM, I/O ports
•for applications in which cost, power and space are critical
•single-purpose (control-oriented)
•Low processing power
•Low power consumption
•Bit-level operations
•Instruction sets focus on control and bit-level operations
•Typically 8/16 bit
•Typically single-cycle/two-stage pipeline
Microcontroller

14.  8051
 Microchip Technology PIC
 Atmel AVR
 Texas Instruments MSP430 (16-
bit)
