27. 27 Who manufactures Microprocessors/Microcontrollers

28. MP/MC Manufacturers

29. MP/MC History Intel 4004 MP-world’s first MP(1971) 2300 transistors Intel 8008Mp Intel’s ATOM Intel 8080 Intel 8085 Intel 8086(16 bit MP) Intel 80186(16 Bit MP) Intel 80386(32 Bit MP) Intel Pentium 4 Intel’s 8031Intel’s 8051 ATOM processor has 47 Million transistors, on a space less than 26square mm 8086 processor has 29000 transistors, 80386 has 275,000 Transistors Intel 80286(32 Bit MP) ATTINY10 PIC MCs

30. Moore’s Law Dr. Gordon E. Moore co- founded Intel in 1968. His observation that number of transistors doubled every 2 years became known as “ Moore ’ s Law ”

31. MP/MC Packages Intel’s ATOM-BGA Package Pentium III-BGA package Intel 8085-40 pin DIP Intel 4004 MP-world’s first MP(1971) 2300 transistors(16 Pin DIP)

32. Different IC Packages (Continued)

33. 33 Let us take an example from applications what we discussed sofar

34. 34 What is a Microprocessor Microprocessor is a

35. 35 Microprocessors General-purpose microprocessor CPU for Computers No RAM, ROM, I/O on CPU chip itself Example ： Intel’s x86, Motorola’s 680x0 CPU General- Purpose Micro- processor RAMROM I/O Port Timer Serial COM Port Data Bus Address Bus General-Purpose Microprocessor System Many chips on mother’s board

36. 36 What is a Microcontroller ? Microcontroller is a

37. 37 Microcontroller: A smaller computer On-chip RAM, ROM, I/O ports... Example ： Motorola ’ s 6811, Intel ’ s 8051, Zilog ’ s Z8X and PIC 16X RAM ROM I/O Port Timer Serial COM Port Microcontroller CPU A single chip

38. 38 What is the difference between Microprocessors and Microcontroller

39. 39 Microprocessor vs Microcontroller Microprocessor 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 Microcontroller CPU, RAM, ROM, I/O and timer are all on a single chip fix amount of on-chip ROM, RAM, I/O ports for applications in which cost, power and space are critical single-purpose

40. 40 MP/MC Architecture RISC CISC Harvard Von Newmann

41. 41 RISC (Reduced Instruction Set Computing Processor)

42. 42 CISC (Complex Instruction Set Computing Processors) Numerous Instruction Group Numerous Addressing Modes Microcoded Instructions Microcontrollers and Microprocessors are CISC based. DSP’s are closer to RISC.
