PIC usually pronounced as "pick" is a family of microcontrollers made by Microchip Technology , derived from the PIC [1] [2] [3] originally developed by General Instrument 's Microelectronics Division. All current models use flash memory for program storage, and newer models allow the PIC to reprogram itself.

Nowadays, Microcontrollers are so cheap and simply obtainable that it is general to use them instead of easy logic circuits like counters for the sole reason of gaining some design flexibility and discount some space. Some machines and robots will even rely on a huge number of microcontrollers , each one enthusiastic to a confident task. A micro-controller can be comparable to a little stand alone computer; it is an extremely powerful device, which is able of executing a series of pre-programmed tasks and interacting with extra hardware devices.

Difference between Microprocessor and Microcontroller

Their interfacing with other peripherals is also very easy. I recommend you to check a list of Pic microcontroller project here. Each family has a variety of components along with built in special features.

It offers a lot of memory sizes and pin packages and different clock ratings. Memory is used for storing the instructions after processing. Control unit is used to control the internal and external peripherals which are connected to the CPU and accumulator is used for storing the results.

PIC microcontroller memory module consists of mainly 3 types of memories:. It contains the written program after we burned it in microcontroller. Program Counter executes commands stored in the program memory, one after the other. Pic microcontroller can have 8K words x 14 bits of Flash program memory that can be electrically erased and reprogrammed. Whenever we burn program into the micro, we erase an old program and write a new one.

It is a RAM type which is used to store the data temporarily in its registers. The RAM memory is classified into banks. Each bank extends up to 7Fh bytes. Number of banks may vary depending on the microcontroller. PIC16F84 has only two banks.

The lower locations of each bank are reserved for the Special Function Registers and upper locations are for General Purpose Registers. These are used for general purpose for multiplying, addition or subtraction and then storing the results in other registers.

CPU can easily access the data in these registers. Their function is set at the time of manufacturing. They perform the function assigned to them and user cannot change the function of SFR. Three important SFRs for programming are:. This memory allows storing the variables as a result of burning the written program. It is readable and writable during normal operation over the full VDD range.

This memory is not directly mapped in the register file. It is indirectly addressed through the SFRs. The transfer of one bit of data at time consecutively over a communication channel is called Serial Communication. There are three protocols of serial communication:. Timers and counters are important as timers can tell the time and count. These timers work according to the selected modes. There are no analog outputs in PIC Microcontroller. It can convert 8 bits of digital number from the eight digital outputs of PIC microcontroller.

It converts the analog voltage levels to digital voltage values. Reference voltage of 5V is required for the operation of the converter. Notify me of follow-up comments by email.

AVR is a family of microcontrollers developed since by Atmel , acquired by Microchip Technology in AVR microcontrollers find many applications as embedded systems. They are especially common in hobbyist and educational embedded applications, popularized by their inclusion in many of the Arduino line of open hardware development boards. Atmel says that the name AVR is not an acronym and does not stand for anything in particular. The designers worked closely with compiler writers at IAR Systems to ensure that the AVR instruction set provided efficient compilation of high-level languages. Among the first of the AVR line was the AT90S, which in a pin DIP package has the same pinout as an microcontroller, including the external multiplexed address and data bus.

When it comes to choosing microcontroller, it is really a confusing task as there are various microcontrollers available in the market with same specifications. So every parameter becomes important when it comes to selecting a microcontroller. Here they are compared on various levels which will be helpful in selecting microcontroller for your project.

A microcontroller is a chip optimized to control electronic devices. It is stored in a single integrated circuit which is dedicated to performing a particular task and execute one specific application. It is specially designed circuits for embedded applications and is widely used in automatically controlled electronic devices. In this Microprocessor Vs.

Nsa. dov Переведя взгляд на рабочий кабинет Стратмора, она поняла, что больше не может ждать, пусть даже помешает его разговору по телефону. Она встала и направилась к двери. Хейл внезапно почувствовал беспокойство - скорее всего из-за необычного поведения Сьюзан. Он быстро пересек комнату и преградил ей дорогу, скрестив на груди руки. - Скажи мне, что происходит, - потребовал .

 Не знаю, я его не видела. - Господи Иисусе, - простонал Стратмор.  - Ну прямо цирк.  - Он провел рукой по подбородку, на котором темнела полуторасуточная щетина.  - А что Следопыт. Я сижу у себя точно на раскаленных углях.

В тот момент она поняла, что нашла свою любовь - шифры и криптография отныне станут делом ее жизни. Почти через двадцать лет, получив степень магистра математики в Университете Джонса Хопкинса и окончив аспирантуру по теории чисел со стипендией Массачусетского технологического института, она представила докторскую диссертацию- Криптографические методы, протоколы и алгоритмы ручного шифрования. По-видимому, ее работу прочел не только научный руководитель, потому что вскоре последовал телефонный звонок, а затем по почте ей доставили авиационный билет от АНБ. Все, кто имел отношение к криптографии, знали, что о АНБ собраны лучшие криптографические умы нашей планеты. Каждую весну, когда частные фирмы начинают охоту за талантливой молодежью, соблазняя ее неприлично высокими окладами и фондовыми опционами в придачу, АНБ внимательно наблюдает за этим, выделяет наиболее подходящих и удваивает предлагаемую сумму.
