MICROCONTROLLER PPT - pank88s - 10-04-2017 MICROCONTROLLER [attachment=568] What is a microprocessor? The microprocessor is the integration of a number of useful functions.These functions are: The ability to execute a stored set of instructions to carry out user defined tasks. General-purpose microprocessor. Act as CPU for Computers. No RAM, ROM, I/O on CPU chip itself Example Intel s x86, Motorola s 680x0 What is Microcontroller? Microcontroller is a device which integrates a number of the components of a microprocessor system onto a single microchip. So a microcontroller combines onto the same microchip : The CPU core Memory (both ROM and RAM) Some parallel digital I/O Microprocessor vs Micro-controllers Microprocessors High end of market where performance matters High power dissipation high cost Need peripheral devices to work Mostly used in microcomputers. Embedded Systems Embedded system means the processor is embedded into that application. An embedded product uses a microprocessor or microcontroller to do one task only. In an embedded system, there is only one application software that is typically burned into ROM. Example printer, keyboard, video game player Criteria in Choosing a Microcontroller Meeting the computing needs of the task efficiently and cost effectively Speed, the amount of ROM and RAM, the number of I/O ports and timers, size, packaging, power consumption Cost per unit 2.Availability of software development tools assemblers, debuggers, C compilers, emulator, simulator, technical support 3.Wide availability and reliable sources of the microcontrollers. |
